Ember-CLI Routing Nesting

I am writing a project using Ember-cli and my nesting views aren't being displayed properly. I have been playing with the routes but can't set the right thing.

The structure of my project is :

http://ift.tt/1AUyIi0

Red Rectangle ---> App Folder in Ember-CLI Project

Blue Rectangle ---> One tab

Green Rectangle ---> Another Tab

You also can see my router.js file

Both Tabs has got their own navigation bars like the following:

Polling-Manager TAB with subtabs Suspension and OptOut (See Image)

http://ift.tt/1AUyIi2

Alerts TAB This tab has got the SubTabs View and Test

It works writing manually the URL in the browser to see each navigation bar but it doesn't clicking in the Main NAVBAR (Alerts and Polling )

P.D : : Ember Debugger says me when I am in one tab and want to change to the other :

Transitioned into 'polling-manager.alert-self-service.index' while I think it should be just 'alert-self-service.index'

Any help or suggestion would be very appreciated.
