Needing watch on initValue to fix ng-model updates problem

ngModel updates do not trigger change event listener
---

In my application, I need to **cancel** my updates on my form.
I do this with a cloned value into my form, and I reset the form to the initial value when form is cancelled.
The ngModel is updated but `ngSwitchery` doesn't do anything on my checkboxes because _**change event is not called on ngModel updates**_.
