Render CollectionView with models from hasMany polymorphic

Hi, First of all I’m relatively new to Ember and I don’t know if what I’m trying is even possible, so feel free to tell me if there is other way.

Right now I have a Page model like this:

BackApp.Page = DS.Model.extend({
  name: DS.attr('string'),
  title: DS.attr('string'),
  url: DS.attr('string'),
  createdAt: DS.attr('date'),
  modules: DS.hasMany('modules', {inverse: 'page', polymorphic: true, async: true})
});

Which has many modules of different type (I’m only showing these for brevity):

BackApp.Module = DS.Model.extend({
  name: DS.attr('string'),
  type: DS.attr('string'),
  page: DS.belongsTo('page', {inverse: 'modules'})
});

BackApp.ClaimsModule = BackApp.Module.extend({
  title: DS.attr('string'),
  text: DS.attr('string'),
  other: DS.attr('string')
});

BackApp.BasicModule = BackApp.Module.extend({
  title: DS.attr('string'),
  text: DS.attr('string'),
  moreStuff: DS.attr('string')
});

What I am trying to accomplish is, on the edit page route, to render views to be able to manipulate the modules directly (each module of different type should render a different type of view). Right now, I’m trying to make this with a CollectionView, but I’m not having any luck so far:

Inside the page.edit template I have:

{{render 'modules' modules }}

I have a ‘modules’ controller:

BackApp.ModulesController = Ember.ArrayController.extend({
  // Implement your controller here.

  init: function(){
    console.log('init modules controller');
  },

  lookupItemController: function( object ) {
    console.log('in lookup init controller');
  }

});

And a ModulesView:

BackApp.ModulesView = Ember.CollectionView.extend({

  init: function(){
    console.log('init modules view');
  },

  createChildView: function(viewClass, attrs) {    
    return this._super(BackApp.ModuleView, attrs);
  }
});

I tried to debug whether the createChildView from the ModulesView or the lookupItemController from the ModulesController were triggered, but neither was, so I guess I’m messing it up with the render itself.

Thank you in advance.
