The only call here is that you need to check your JavaScript code. It seems like you're preventing the form to be submitting, it might be because of
return false;
inside the block where you're capturing the form submit event, or you're trying to prevent it like this
event.preventDefault();
.. the last bid would be that you're capturing the event by ClientSide function and there is some error in your code which is causing nothing to happen at all. I would advise you to open the Console, using F12 and then checking what happens when you press the button. It will surely tell you if there is any kind of error in the form submission process.
