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

Hi, I'm struggling to solve this challenge. Not entirely clear how render and ngModelCtrl are controlling the input.

Please let me know if you have any tips.

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

      }

    }
  }
});
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>

Very close. The challenge was to console.log the users input. Which you have in the variable userInput. However you're outputting $render.

Instead try:

console.log(userInput);
