# Attaching a handler to the element's `confirm` event that returns a `falsy` value cancels the confirmation dialog.
# Attaching a handler to the element's `confirm:complete` event that returns a `falsy` value makes this function
# return false. The `confirm:complete` event is fired whether or not the user answered true or false to the dialog.
