New ember js pre 4 problem

gistfile1.js

App.DashboardController = Em.ArrayController.extend({
  content: [],
	
	contentRecent: Em.ArrayController.create({
		content: [],
		count: Em.computed(function() {
			return this.get('content').length;
		}).property('content.@each')
	}),

App.DashboardController = Em.ArrayController.extend({
  content: []
});

App.RecentItemsController = Em.ArrayController.extend({
  content: [],
  count: Em.computed(function() {
    return this.get('content').length;
  }).property('content.@each')
});

// In your route:

App.DashboardRoute = Em.Route.extend({
  setupController: function(controller, model) {
    // The `controller` argument is the controller matching the route's name,
    // in this case the `DashboardController`'s instance
    this.controller.set('content', ["a", "b", "c"]);
    this.controllerFor('recentItems').set('content', ["d", "e", "f"]);
  }
});

Fuck, forgot the -Controller from the RecentItems. Of course, it's RecentItemsController...
Updated the example.
