Simple Ember + Ember Data + Rails App

I'm trying to use ember together with Rails, but getting an strange error.

It's a very simple nested route test.

I have a rails resource named "Post", just like the video on ember docs:

https://github.com/tildeio/bloggr-client and I've got almost everything working.

http://domain.com/admin#/posts/ works fine

clicking on a post, shows me the details, change the url.

but when I try to load it directly:

http://domain.com/admin#/posts/1

The error happens.

This is my console output:

DEBUG: ------------------------------- ember.js?body=1:382
DEBUG: Ember.VERSION : 1.0.0-rc.7 ember.js?body=1:382
DEBUG: Handlebars.VERSION : 1.0.0 ember.js?body=1:382

 ember.js?body=1:382
Uncaught <(subclass of App.Post):ember269:1> 

The strange thing is the url that ember is generating, http://domain.com/post)s/1

Where is this ) comming from?

This is my js:

//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require bootstrap_bootstrap
//= require chosen-jquery
//= require bootstrap-wysihtml5
//= require bootstrap-wysihtml5/locales/pt-BR
//= require handlebars
//= require ember
//= require ember-data
//= require_self

// for more details see: http://emberjs.com/guides/application/
App = Ember.Application.create({
  rootElement: '#ember_root'
});

App.Store = DS.Store.extend({
  revision: 12,
  adapter: DS.RESTAdapter
});

App.Router.map(function() {
  this.resource('posts', function() {
    this.resource('post', { path: ':post_id' });
  });
});

App.PostsRoute = Ember.Route.extend({
  model: function() {
    return App.Post.find();
  }
});


var attr = DS.attr;

App.Post = DS.Model.extend({
  title: attr('string'),
  description: attr('string')
});

//= require_tree .

Edit.:

This is the Json that my app is consuming:

{"posts":[{"id":7,"title":"teste","description":"su o autor"}]}

My views:
