Ember.js / Stage 4 / ObjectControllers & ArrayControllers : what is the solution to the code challenge ?

Hey,

I'm currently learning Ember.js

On stage 4, I have an issue with the last code challenge : I cannot figure out why my code does not pass.

Here is below my solution :

AnimalShelter.KittensController = Ember.ArrayController.extend({
  actions: {
    sortByCuteness: function() {
      this.set('sortProperties', ['cutenessRating']);
    }
  }
});

Any clue ?

Thanks

ps : below is the full code, including my solution. I even added a Handlebars helper in index.html

js/app.js 
AnimalShelter = Ember.Application.create();

AnimalShelter.Router.map(function() {
  this.resource('kittens', {path: '/'});
});

var kittens = [
  {id: '1', name: 'Meowzer', cutenessRating: 2},
  {id: '2', name: 'Squeaky', cutenessRating: 3},
  {id: '3', name: 'Fluffy', cutenessRating: 1}
]

// your code here

AnimalShelter.KittensController = Ember.ArrayController.extend({
  actions: {
    sortByCuteness: function() {
      this.set('sortProperties', ['cutenessRating']);
    }
  }
});
index.html 
<!DOCTYPE html>
<html>
<head>
  <title>Animal Shelter</title>
</head>
<body>
  <script src="js/libs/jquery-1.10.2.js"></script>
  <script src="js/libs/handlebars-v1.3.0.js"></script>
  <script src="js/libs/ember-1.8.1.js"></script>
  <script src="js/app.js"></script>

  <script type="text/x-handlebars" id="kittens">
    <h1>Kittens</h1>
    <p><a href="a" {{action 'sortByCuteness'}}>Sort By Cuteness</a></p>
  </script>

</body>
</html>

Hi Antoine!

You're on the right track here but this challenge is only asking you to set the default sort — you don't need an action like in the previous video.
