Hello there Vinay,
Look, I've seeing a lot of implementations like the one you are trying to build up, but if you really need some good implementation for AJAX using ASP.Net, I'd suggest you to dig into both IHttpHandlerFactory and IHttpHandler interfaces... forget about this Page Methods implementation cuz it does sucks.
Good luck!
