rewrite addEvent function signature to work with removeEvent using variable that points to function

addEvent-removeEvent.js

function openHandler(widgetTypeId, userWidgetId, displayOrder, savePrefUrl) {  
  // some stuff
  
  Utils.addEvent(btnSave, 'click', function () {
      btnSaveClick(widgetTypeId, userWidgetId, displayOrder, savePrefUrl);
  });
}

function btnSaveClick(typeId, widgetId, order, url) {
  // definition
}


/* Can be rewritten to below? */
var saveClickHandle = function() {
  btnSaveClick(widgetTypeId, userWidgetId, displayOrder, savePrefUrl);
}

Utils.addEvent(btnSave, 'click', saveClickHandle);
