Done.

       cancelButton.addEventListener('click', function(e) {
         chrome.send('resetOnCancel');
         e.stopPropagation();
       });
       buttons.push(cancelButton);

     },

+    /**

      */
     cancel: function() {
       chrome.send('resetOnCancel');
     },
   };
 
   return {
     ResetScreen: ResetScreen
   };
 });
