If you have a Handle which is known to be persistent you should use the Persistent::Cast to cast it to a Persistent handle and then call ClearWeak.
Persistent::Cast(some_handle_whish_is_known_to_be_persistent).ClearWeak(); If you use Persistent::New a new persistent handle will be created pointing to the same object and the existing one with the weak callback registered will still be in existence causing the callback to be called.
