How can I expose my own classes to cegui lua by luabind?

[q68576021]

I try to expose my own classes to cegui lua, and in this way, i can easily handle the event with gui and my game.
However, it failed when i try to bind my function using luabind.
What happened? Could anyone tell me how to do this? Thanks for your help.
