Material: md-datepicker: Date not updated on model updates

[dratchkov]

Hi,

The date display is not getting updated when the model value is updated externally. See fiddle here.

Is there a workaround for this?

Thanks,

Hey @dratchkov,

You can find more information on a previous tracked issue on AngularJS https://github.com/angular/angular.js/issues/13224

Just summarizing:

• The problem is, when you increment the day value, the actual date object will have the same reference id, so ngModel won't detect it.
• Because ngModel will always compare $viewValue with $modelValue (See here) it won't detect any change.
• So as you can see in the demo below (or in the issue) you should create a clone of the date, which has a new reference id -> and then the ngModelCtrl can detect the change.

Here a little demo - http://codepen.io/DevVersion/pen/zrmeXR
