jQuery UI Dialog

I found a very easy way to submit dialog on enter in your UI DIalog,
hope someone will use it :)
function:
function form_click_enter(form)
{
    var dialog = $(form).parent("div").siblings("div.ui-dialog-
buttonpane");
    $("button:first",dialog).click(); // right one
}
and typical html you need to put in your dialog:
    <form id="add_place_form" onsubmit="javascript:form_click_enter
(this);" action="javascript:;">
here inputs etc...
    </form>
It works really fine for me.
