It has nothing to do with IE.
When you add an event on to page elements, like the .click event, that applies only to the existing elements on the page. New elements added on to the page do not have that event added to them.
jQuery has a plugin called liveQuery so that you can tell jQuery that certain groups of elements are to be watched, so that an event can be added to elements that are added to the page via jQuery.
Read the jQuery FAQ entry, [Why doesn't an event work on a new element I've created? and the [URL="http://docs.jquery.com/Plugins/livequery"]liveQuery documentation](http://docs.jquery.com/Frequently_Asked_Questions#Why_doesn.27t_an_event_work_on_a_new_element_I.27ve_created.3F) page.
