In angularJS you'll bind the object property to the input using ng-model. There's no need to listen any change, because the framework takes care of that.

¿Who provides this object to the <input>? The controller, exposing the object through this.

Here's a working example using components.

As you can see, you'll need to use bracket notation because of the use of spaces on your object keys...

<input ng-model="$ctrl.obj['Display Name']">

On a real world example, I suppose your data will be provided using a service, as you can see in this example:

Hope it helps!

/*HTML: */ <input ng-model="firstName" type="text" class="editable">

/*Angular: */   var contactToEdit = outText.find(x => x["Display Name"] === $scope.disName);    contactToEdit["First Name"] = $scope.firstName;

What if I do this way. Isn't it an effective approach

but when do you tell angular to do the assignment? if you're thinking on ng-change, that's we wanted to avoid, and that's what ng-model is for...
