ajax_submit wasn't working

Troubleshooting a problem I was running into I believe that this code in fivestar.module line 492:

    $votes = _fivestar_cast_vote($form_state['settings']['content_type'], $form_state['settings']['content_id'], $form_state['values']['vote'], $form_state['settings']['tag']);
  }

Should be changed to be sending in the entity_type, not content type:

    $votes = _fivestar_cast_vote($form_state['settings']['entity_type'], $form_state['settings']['content_id'], $form_state['values']['vote'], $form_state['settings']['tag']);
  }

Hope that helps someone. Mine works now.
