title: get all bindings of templete in ember
body: <p>Is there a way to get all bindings of all fields or checkboxes of a template in ember ?
  The intention is to get them in a generic way, to store them in a generic way in a json object and to send them to the server. The server maps the variable names to the model attributes. Something like I call a function from the controller with the template name and get back all bindings ?  </p>
  
  <pre><code>get_bindings("templatename":"test_template")
  </code></pre>
  
  <p>How should this method look like ?</p>
