Call ng-change when the model has changed in the angular component

Question

I have an upgrade to angular 1.5 and now you want to use components instead of directives. My problem is that my ngModel will not run ng-change after I change my value. all solutions found did not match my problem.

i has the following component

<date-picker ng-model="$ctrl.fromDate" ng-change="$ctrl.updateData()">
</date-picker>

my date picker directive looks like (I reduced the code because there are a lot of irrelevant things) I use babelify for my code

import template from './datePicker.jade';
import moment from 'moment';

class datePicker {

  constructor(
    $scope,
    $element,
    $attrs
  ) {
    console.log(this);
    this.$scope = $scope;
    this.$element = $element;
    this.$attrs = $attrs
    this.initialize();
  }

  initialize() {
    this.updateView();
  }

  changeDate(day) {
    this.ngModel = day;
    this.updateView();
  }

datePicker.$inject = [
  '$scope',
  '$element',
  '$attrs'
];

export default {
  controller: datePicker,
  bindings: {
    ngModel: '=',
  },
  template: template(),
};

My solution with a directive method defined the scope.updateModel function in the link function, which sets the view value of my model. It works, but its ugly, I no longer want to use link functions
