According to the information provided on w3schools website:
The ng-change event will only be activated if there is an actual alteration in the input value, not if the change was executed through JavaScript.
Therefore, when I set up ng-model using $scope in my controller, ng-change does not activate.
Any suggestions?
Modificationin the model value controlled by the controller will not trigger a change event on the DOM, which is the expected behavior. Typically, events are attached to the DOM rather than to changes in values.
The ng-change event is a directive provided by Angular for adding a change event to input/select elements in a declarative manner.
This means that the ng-change handler will only be activated when there is a modification in the value of the input/select element.
<input type="text" ng-change="changesHappen()" ng-model="testModel"/>
