code: def func_on_enter(func):
      
      def function_after_enter_pressed(ev):
          ev.stopPropagation()
  
          # if the key was `enter` ..
          if ev.keyCode == 13:
              func(ev)
  
      return function_after_enter_pressed
docs: Register the `func` as a callback reacting only to ENTER.
  
      Note:
          This function doesn't bind the key to the element, just creates sort of
          filter, which ignores all other events.
