does mousedown /mouseup in jquery work for the ipad?

I am using the current code:

$('body').mousedown(function() {
        $('div#extras').fadeTo('fast', 1);
});

$('body').mouseup(function() {
        $('div#extras').delay(2000).fadeTo(1500, 0);
});

This works great in safari but when I upload it and check it out on the ipad it doesnt work?
