Have you tried to debug it to see where it goes on client and server side?
Are you aware of the post-back issue? (AJAX)

Can you please share like if your ajax is throwing any error. if it's separate JS file, please check if the file is loaded.

OnClientClick="return ValidateFunction()

OnClientClick function which we write in javaScript execute on client side before control passed to server and after that

OnClick=" btnSubmit_Click"

executes on the server if your

ValidateFunction()

returns true.

try to debug your javascript validateFunction on server and check what it is returning.
