seems to work fine First off, your goToPage in your route isn't taking any parameters, so pageNumber is undefined there.
code :
//the route 
    goToPage: function(pageNumber) {
        this.set('page_number', pageNumber);
        return this.refresh();
    } 
//the component
goToPage: function() {
    var pageNumber = this.get('pageNumber');
    if (pageNumber >= 1 && pageNumber <= this.get('lastPage')) {
        this.sendAction('goToPage', pageNumber);
    }
}
Emberjs only rerender component after observer in view is triggered

help you fix your problem Following the OP design, a simple approach to refresh only the component is by getting it from the view and calling rerender on that. To get the component from the view just add a viewName.
For example,
code :
....{{form-error errors=fooErrors foo=model field="fooId" viewName="theErrorsCmp"}}
export default Ember.View.extend({
  errorsChanged: function() {
//if this fires for some reason at the very beginning before the view has been inserted to the DOM and the component is not yet available then just check before using it, i.e. uncomment the following line
//if(!Em.isEmpty(this.get("theErrorsCmp")))
    this.get("theErrorsCmp").rerender();
  }.observes('controller.fooErrors')
});

should help you out You are not passing your action name properly.
You need to be aware that the sendAction method will fail silently if it can't find the action name.
code :
{{#bootstrap-modal title="Sign In" ok='signin' okText="Signin" removeModal="removeModal"}}

may help you . Option 1. You need to define action authenticate in actions hash of auth-login component.
Option 2. You can keep identification, password properties and authenticate action in controller. and include the auth-component like below,
code :
{{auth-component identification=identification password=password authenticate="authenticate" }}
import Ember from 'ember';
export default Ember.Component.extend({
    actions: {
        authenticate() {
            this.sendAction('authenticate'); //this will call corresonding controller authenticate method through bubbling.
        }
    }
});
import Ember from 'ember';

export default Ember.Controller.extend({
  session: Ember.inject.service(),

  actions: {
    authenticate: function() {
      var credentials = this.getProperties('identification', 'password'),
        authenticator = 'authenticator:jwt';

      this.get('session').authenticate(authenticator, credentials).catch((reason) => {
        this.set('errorMessage', reason.error || reason);
      });
    }
  }
});

code :
{{cs2i-cardcomponent card=card index=index enableNext='enableNext' tagName="li" selectCard=(action "selectCard" card index)}}
