How do I use ngModelCtrl to send all new values typed into an <input> to the console.log ?

In Angular, I need to write a function that uses the ngModelCtrl to send all new values typed into the <input> to the console.log function. I have no idea how to approach this. Please help.

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) {

      // YOUR CODE HERE

    }
  }
});
index.html
<!DOCTYPE html>
<html ng-app="myApp">
<head>
  <title>Angular.js</title>
  <script src="js/angular.js"></script>
  <script src="app.js"></script>
</head>
<body ng-controller="myController">

  <p>Hello {{user.name}}</p>
  <input type="text" ng-model="user.name" />
  <div my-directive ng-model="user.name"></div>

</body>
</html>

I figured it out:

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