The event $scope.$on('$destroy') doesn't work updating ionic & angular

I think the issue was by ths following , Is your template cached? If you don't have cache: false in your state routes, then the controller is not destroyed.

it fixes the issue I was able to fix this problem by adding the "chartjs":"~1.0.1" line in the bower.json file located at the root of my app.
code :
{
  "name": "com.companyname.appname",
  "private": "true",
  "devDependencies": {
    "ionic": "driftyco/ionic-bower#1.0.0-beta.14",
    "platform": "~1.3.0",
    "chartjs": "~1.0.1"
  },
  "dependencies": {
    "angular-chart.js": "~0.3.14"
  }
}
$scope.$watch in Angular doesn't work in Ionic/Cordova

$scope.$watch in Angular doesn't work in Ionic/Cordova

will help you Possible reason for not working $scope.$watch might be property overriding in child scope. If you set $watch on controller scope, but checkbox with ng-model binding is created inside some child scope of the controller, child scope might create its own mail property and controller $scope.$watch will not be able to detect changes in that property. Here is jsfiddle that demonstrates this problem: link.
To avoid this problem you should not use primitive values on the scope for ng-model bindings. Instead you should bind to properties of objects on the scope, for example ng-model="formData.mail" where formData is some object in the controller's scope. To watch for object property changes you also use dot syntax: $scope.$watch('formData.mail', function(){...})
Ionic/Angular 2 component event emitter not updating view

Ionic/Angular 2 component event emitter not updating view

I hope this helps you . I think that it's because Angular2 detects changes based on references and not on values. If a new instance of date is detected, the view will be updated. If it's the same instance but its content is updated, the view won't be updated.
I would recreate a new date like this:
code :
DatePicker.show({
  date: new Date(self.date),
  mode: self.mode
})
.then(
  (date:any) => {
    if (!date) {
      date = previousDate;
    }
    self.onUpdate.emit(new Date(date.getTime()));
  },
  err => {
    console.log('error -', err);
  }
);
export class HSDatePicker {

    date:any;
    dateFormat:any;
    label:string;
    mode:string;
    onUpdate:any = new EventEmitter();

    constructor(private ngZone:NgZone) { // <-------
    }

    selectDate() {
      this.ngZone.run(() => { // <------
        let self:any = this;
        let previousDate:any = self.date;

        DatePicker.show({
            date: new Date(self.date),
            mode: self.mode
        })
        .then(
            (date:any) => {
                if (!date) {
                    date = previousDate;
                }
                self.onUpdate.emit(date);
            },
            err => {
                console.log('error -', err);
            }
        );
      });
    }

like below fixes the issue Update selectItem to this ( = is assassin operator and == or === is equal operator)
code :
selectItem(item: any) {

console.log(item);

if (item.colorCode == '#CA3433') {
  item.colorCode = '#3342FF';
}
else if (item.colorCode == '#3342FF') {
  item.colorCode = '#CA3433';
}

console.log(item);
}
DOM not updating when click/tap event is executed using Ionic and Angular

DOM not updating when click/tap event is executed using Ionic and Angular

this one helps. Based on your comments it looks like you are not updating the correct counters. When you loop over the userData in the template, you need to update the correct data it is referencing, not extra properties that you have created that are not accomplishing anything.
First off we need to keep track of the index in the ngFor so we know what user to update
code :
<ng-template *ngFor="let tal of userData; let i = index;">
<ion-card class="ion-card-custom" (click)="increaseCount(i)">
    <ion-item>
        <ion-icon name="pin" slot="start" ></ion-icon>
        <ion-label>{{ tal.title }}</ion-label>
        <section class="tally-info-count" >{{ tal.count }} </section>
        <section class="tally-info-count" >{{ tap }} </section>
        <ion-button fill="outline" slot="end" class="info-button"> i </ion-button>
    </ion-item>
    <ion-item>
        <ion-label>{{ tal.created }} </ion-label>
        <p> {{ plus }} </p>
    </ion-item>
</ion-card>
import { getLocaleDateTimeFormat } from '@angular/common';

//decorator
@Component({
    selector: 'app-tally',
    templateUrl: 'tally.html',
    styleUrls: ['tally.scss'],
  })

export class Tally implements OnInit {
  userData: any[];

  constructor() { }

  ngOnInit() {
    const dateTime: Date = new Date();
    const created: string = `${dateTime.getUTCMonth() +1}/${dateTime.getDay}/${dateTime.getUTCFullYear()}`;
    this.userData = [
        {
            id: 0,
            title: "Title1",
            count: 0,
            created: created
        },
        {
            id: 1,
            title: "Title2",
            count: 0,
            created: created
        }
    ]

  }

  increaseCount (index: number) {
    const specificUserData = this.userData[index];
    specificUserData.count++;
  }
}
