JavaScript AngularJS An Introduction to Two-Way Data Binding Two-Way Binding: ngModelCtrl

Perhaps misleading instructions?

The challenge was for us to write code that would send newly typed values into <input/> to the console.log.

This was the "correct" answer. In the link function....

ngModelCtrl.$render = function() {
   var contents = ngModelCtrl.$viewValue;
   console.log(contents);

}

I am of course happy that I had the "correct" answer, but my code simply reads the property and prints that value to the console.log. It does not -- I don't think - read the newly typed values in the <input> element. Or am I misunderstanding something?

app.js 
angular.module('myApp', [])
.controller('myController', function($scope) {
  $scope.user = {
    name: 'Alex'
  };
})
.directive('myDirective', function () {
  return {
    require: 'ngModel',
    priority: 1,
    link: function ($scope, $element, $attrs, ngModelCtrl) {
      ngModelCtrl.$render = function(){
        var contents = ngModelCtrl.$viewValue;
        console.log(contents);
      }

      // YOUR CODE HERE

    }
  }
});
