subdirectories within ember controller not working

from this post it seems that sub directories within ember controller should work.

http://ift.tt/1IrTJQW

however its not working for me .

here is my code branch like (directory cm contains a child directory views):

 /controllers/cm/views/item.js
 /routes/cm/views/item.js
 /templates/cm/views/item.js

when i try to populate the model in route using the code below i see the data but when i put the same code in controller it never gets executed.

   model: function(){

            return this.store.find('item',{id: "1"});

          }

entry in router.js is as follows:

   this.resource('cm', {path: '/cm/:id'} , function() {

                this.route('views');
                this.route('views.items', {path: '/views/items'});
       });

Clearly ember is not able to resolve the controller correctly. Not sure how to fix this ...
