I've built a listener to prevent a form from submitting on a special ocasion.

I'm using google maps autocomplete api and basically I don't want to submit the form when the users press enter and the recommended results box is displayed. As the users are pressing enter to choose a value from the dropdown box and not to submit the form.

I've built a listener that catches the event correctly but I don't know how to prevent the form from being submitted.

$('body').live('keydown', function(e) {

    if($(.pac-container).is(:visible) && event.keyCode == 13) {

        e.preventDefault(); // Prevent form submission

        }

    });

I tried with e.preventDefault(); but it still submits the form. The form ID is: updateAccountForm

How can I prevent it from happening?

EDIT:
I must point out that it seems that listening for keypresses directly on the search input conflicts with Google API invalidating the autocomplete functions. So no $('input#search') keydown/keypress is possible
