Hi the code isn't right. you're not console logging like it asks.

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

This part isn't required

$element.hallo('setContents',contents);

And should be replaced with this

console.log(contents);
