I have a page, which upon clicking a specific link a jquery ui dialog is opened, works perfectly, in said dialog there is a form(a user registration form), and I need to attach a submit event handler on that form, but because it is loaded with ajax in jquery the event handler will NOT attach, my code is such as this: $("#register").on("submit", false); I just need to be able to cancel the form submission within the dialog and i cannot get it to work.
