javascript - Pass function in ng-model

Is it posible to pass function into ng-model, for example

<input type="text" name="email" class="form-control" ng-model="createModel('email')" ng-change="addProperty(email,'email')" email required placeholder="Email">

ng-change is working fine, but ng-model="createModel(email)" is showing this error

> Expression 'createModel('email')' is non-assignable. Element: <input
> type="text" name="email"....

In controler i have : // I just want to pass value for now

  $scope.createModel = function(modelName){
     console.log("Model name"+modelName);
  }

I saw examples on the internet that people doing this

Looks like AngularJS added "getter" "setter" support in version 1.3

You can scroll to the bottom of their ngModel documentation page at:

https://docs.angularjs.org/api/ng/directive/ngModel

This allows you to specify a method instead of a variable in your ngModel attribute. The method should take an optional parameter. If an argument is passed it should store that value, if no argument is passed it should return a value.

You can see an example in another Stack Overflow answer at: https://stackoverflow.com/a/28224980/984780
