Form value change listener

Hi all,
I have an issue submitting the form. I have a page with a form on it and I want to add a value change listener for it so that when user leaves the page, if there is any change, it will notify if user wants to save the form or not.
I try form.addListener(new ValueChangeListener(){...}) and it doesnot work (of course).
Any idea?
