AngularJs two-way-data-binding not working for custome directive input elements

Does that help Your directive only knows build variable since your (isolated) scope is defined like this:
code :
 scope:{
        build:"=", 
      },
scope:{
            build:"=", 
            buildData:"="
          },
<build-input build="build" build-data="buildData" ></build-input>

should help you out You just need to specify the parameter inside your function call. See this related question: calling method of parent controller from a directive in AngularJS
code :
<button ng-click="addQuestionClick({item: default})" type="button" class="btn btn-default btn-md" id="btnSelect" >
...
<li ng-repeat="item in dropdown">
  <a ng-click="addQuestionClick({item: item})">{{item}}</a>
</li>

hop of those help? I am stuck with two way data binding from directive to controller. Directive is with ng-repeat. Tried several things but cant get directives scope variable reflect back in controller. , Put them in an object like this:
code :
$scope.viewModel = {
  crossTabs: [1, 2, 3, 4, 5]
};
<cross-tab ng-repeat="crossTab in viewModel.crossTabs" cross-tab="crossTab" cross-tabs="viewModel.crossTabs">

Hope that helps After researching for entire day, I ended up here. If someone is having any trouble with Angularjs scope, I highly encourage to read it.
The proper solution in my case was to wrap selected_contents by an object. e.g.
code :
$scope.selected = {};
$scope.selected.contents = [];

hope this fix your issue The problem is caused by javascript prototype inheritance (the long answer). The usual hack is to change a property inside:
This stays the same:
code :
scope: {
    showRecordVideo: '='
},
$scope.showRecordVideo = {
    state: true
};
$scope.showRecordVideo.state = false;

I hope this helps you . If the directive's name is "directive" and the containing controller's scope has the properties "eventAdmin" and "eventId" then this should be working.
I made a JSFiddle of your example: https://jsfiddle.net/Royar/qu55ujj5/4/
code :
<div ng-app="myApp" ng-controller="myCtrl">
  <directive event-admin="{{eventAdmin}}" event-id="{{eventId}}"></directive>
</div>
var myApp = angular.module('myApp', []);
angular.module("myApp").controller("myCtrl", function($scope) {
  $scope.eventAdmin = "aaa";
  $scope.eventId = "bbb";

});
angular.module("myApp").directive("directive", function() {
  return {
    scope: {
      eventAdmin: "@",
      eventId: "@"
    },
    template: "{{eventAdmin}}",
    link: function(scope, element, attrs) {
      console.log(scope.eventAdmin); //working
    }
  };
});
