How do I use jQuery for click event in iPhone web application

When I use jQuery for a simple click event it only works for links. Is there a way to make it work for spans etc:

$("span.clicked").live("click", function(e){alert("span clicked!")});

$("a.clicked").live("click", function(e){alert("link clicked!")});

The SPAN works in Safari but not Mobile Safari (on iPhone or iPad) whereas the A tag works in both.
