Rahul - please copy and paste the pushbutton callback code to your question so that we can see what you have attempted to do. As well, please elaborate on what you mean by its not working. Are you observing an error, or is nothing happening? Try putting a breakpoint in the callback and then stepping through the code to see what is happening.
