Event handling in Ruby

Answer 1

I think you may be trying to reinvent the wheel here. I would recommend using Observable instead. It's in the standard library, just require "observer" and include the Observable module into your class.

Answer 2

Lol, ok i solved the problem... i wasnt calling listen_event correctly...

it should be listen_event(:indexChanged,method(:sayIndex)) not listen_event(:indexChanged,sayIndex(:index))
