Handlebars error: Could not find property 'query-params' although Feature activated

I am trying to use query-params in my route / controller but the handlebars helper is causing this error: Uncaught Error: <(subclass of Ember._MetamorphView):ember689> Handlebars error: Could not find property 'query-params' on object . This error is caused by this link to helper: ``` {{#link-to 'betround.stats' (query-params game=id) }} <li {{bind-attr class="isPast:small"}}> {{team1}} {{scoreT1}} : {{scoreT2}} {{team2}} (gameid: {{id}})</li> {{/link-to }} ``` I have already upgraded Ember and Handlebars ``` DEBUG: Ember : 1.4.0-beta.4 DEBUG: Ember Data : 1.0.0-beta.4 DEBUG: Handlebars : 1.3.0 DEBUG: jQuery : 2.0.3 ``` As well as enabled the query-params-new feature: ``` <script type="text/javascript"> ENV = {FEATURES: {'query-params-new': true}}; </script> <script src="bower_components/jquery/jquery.js"></script> <script src="bower_components/handlebars/handlebars.js"></script> <script src="bower_components/underscore/underscore.js"></script> <script src="bower_components/ember/ember.js"></script> <script src="bower_components/ember-animated-outlet/ember-animated-outlet.js"></script> <script src="bower_components/ember-data/ember-data.js"></script> ``` I am not sure if it is relevant but this is also my controller for the route: ``` GambifyApp.BetroundStatsController = Ember.ArrayController.extend({ needs: "betround", queryParams: ['game'], game: null, filteredBets: function() { var game= this.get('game'); var bets = this.get('model'); if (game) { return articles.filterProperty('game', game); } else { return articles; } }.property('category', 'model') }); ```
