  <p>and i refer to <a href="https://stackoverflow.com/questions/17890439/mapping-json-to-backbone-js-collections">this</a> and no solution satisfied my level of knowledge about backboneJS. </p>
  
  <p>Normally i used to get it like model.get('name') but couldn't get the nested item/object. Anyone can help to get item in the 'drilldown'</p>
