Not working

Somehow this is not working. I think I am doing everything right, I am camelcasing, using $attrs...

I would love to have some help :-)

app.js 
angular.module('myApp', [])
  .controller('myController', function ($scope) {
    $scope.title = 'My embedded title';
  })
  .directive('treehouseCourse', function () {
    return {
      link: function ($scope, $element, $attrs) {

        $attrs.$observe( courseTitle ){
          console.log( courseTitle );
        }

      }
    }
  });
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">

  <div treehouse-course course-title="{{title}}"></div>

</body>
</html>

Hi there Christiano Ronaldo,

$observe takes 2 parameters, where the second is a function.

In this case, we should pass an anonymous function and place the console.log statement within it. console.log should return $scope.title, as well.

I hope that helps. :)
