Login authentication with Ember-cli, Rails and ember-cli-simple-auth-token

I have created a ember-cli project (v 0.1.12) with ember.js (v 1.8.1) and rails. Than I tried to install:

http://ift.tt/1vyeZP9

but when I run the login POST the server respond to me with this error: Can't verify CSRF token authenticity.

I notice that it sends only username and password, without token.

Thanks to everybody!
