Hello Jinyoung,
I have been facing the same problem, and alos posted with no sucess in 
this mailing list.
In order to synchronize 2 renderers, I setup one observer on each 
renderer's camera, osberving the event : vtkCommand::ModifiedEvent
This event triggers a function which forces the other renderer to render.

Hope that it helps, I can send you a small code sample if you need to 
see how to setup callbacks.
