why doesn't delegate work for scroll?

Answer 1

i think this may bind your scroll

$('#child').live('keyup', function() {
var el = $(this);
if (!el.data("has-scroll")) {
    el.data("has-scroll", true);
    el.scroll(function(){
       //doscrollaction(el);
    });
}
doscrollaction(el);
});

as requested by op:

i change the css so child overflows and use jquery.scroll and that works, however there is no 'scroll' event like you have for jquery not that i know of anyway, hence the reason why bin, live etc can not be set for scroll and also why your deligate will not work
