[jQuery] Click Tracking - Works In IE Only

[jQuery] Click Tracking - Works In IE Only


Need to know why this code below records the click in IE but does not
record the click in FF or Safari. a.adBanner is an internal link
within the same domain. Thank you in advance.
$('a.adBanner').live('click',function(){
var provider_id = $(this).attr('id');
var providerid = provider_id.match(/[0-9]+/g);
$.get('../lib/bannerTracking.php', {
pid : providerid
}, function() {
});
});
