title: How do I access session properties in ember-simple-auth?
body: <p>I'm using a custom Facebook authenticator, very similar to the one given in the ember-simple-auth <a href="https://github.com/simplabs/ember-simple-auth/blob/master/examples/7-facebook-auth.html#L91" rel="nofollow">example</a>. I inject the properties <code>accountID</code> and <code>accessToken</code> into the session here: </p>
  
  <pre><code>if (fbResponse.status === 'connected') {
    console.log("AccountID: " + fbResponse.authResponse.userID);
    Ember.run(function() {
    resolve({
       accessToken: fbResponse.authResponse.accessToken,
       accountID: fbResponse.authResponse.userID
    });
  });
  </code></pre>
  
  <p>If I read the <a href="http://ember-simple-auth.simplabs.com/api.html#Ember-SimpleAuth-Session" rel="nofollow">docs</a> correctly, I should be able to access <code>accountID</code> using <code>session.accountID</code> in any controller. But, the only way I can find this is via <code>session.store._lastData.accountID</code>, which is probably not the right way to do it. </p>
  
  <p>More specifically, in a controller, I have an action:</p>
  
  <pre><code>createRental: function() {
        var session = this.get('session');
        console.log(session.accountID); // undefined
        console.log(session.store._lastData.accountID); // '123456'
  </code></pre>
  
  <p>Does anyone with experience using ember-simple-auth know what the issue is? Thanks!</p>
