How to keep the facility in the ctrl + s Ember.js?

How can you save the object in the ember by pressing ctrl + s? It is known to any property . How can I get access to the vault ?

document.body.addEventListener('keydown', function (e) {
   if ((e.keyCode === 83) && (e.ctrlKey)) {
      e.preventDefault();
      var name_obj = get_name_obj(); //name or id or everyone parameter not self object
      console.log('ctrl + s');;
   }
});
