Ember-cli-simple-auth-devise, communicate with the server in an authorized way

I have just created an App with Ember-cli 0.1.12, Rails 4.2, Ember-cli-simple-auth-devise and gem devise.

The Sign-in is succesfully completed, but when I try to get the data from the server it returns to me 'No authorization provided.'

It looks like the server is not receiving the token or the client is not sending it.

To create my App I used this guide:
