Where is EventRegistration release.

Hi, thanks for this lib for c++ eventbus.
I have a question. 
I find that  in AddHandler. it will `:EventRegistration* registration = new EventRegistration`
But in 
`virtual void removeHandler() {
			if (registered) {
				registrations->remove(this);
				registered = false;
			}
		}`
 I do not find use delete to release  it.
Is there a memleak?
Thanks a lot.
