import Ember from 'ember';

Ember.Select.reopen({
 	didRender() {
 			this.notifyPropertyChange('selection');
 		}
 	});

export default Ember.Controller.extend({
  appName: 'Ember Twiddle', 
  allEmployees: [{id: 1, fullName: 'Miguel'}, {id: 2, fullName: 'Ahmed'}],
  // In 1.13 if this isn't initialized  it won't be updated, in prior
