Why Won't MatLab Recognize my COM Application's Events?

I am attempting to set up a COM server with the command

 example = actxserver('Afgrow.Application')

I can successfully set up the server and invoke methods / change data with:

 example.get('ExampleProperty')
 example.set('ExampleProperty')  
 example.invoke('ExampleMethod')

But, when I try to set up events with:

example.registerevent(EventHandlerHandle)

No errors happen, but

 example.eventlisteners

is empty. I then read that you should be able to veiw all possible events with

 example.events

This also returned nothing. Does anyone know a fix?

Thanks,

Jimmy L.
