JQuery failing to provide Success message.

After user enters an email in the email field, the form auto populates other fields. Display a message asks if user needs to update the information. If so, use can update the information (After user hits the Update button, display a message saying your information has been updated. Keep other parts on the screen as it is). Do all these using AJAX/JQuery.
