[jQuery] clicking appended element

[jQuery] clicking appended element


guys,
for example i want to append the <li> element dynamically and attach
the click event
HTML :
<ul id="subs">
</ul>
JS:
$(document).ready(function() {
...
//add dummy data
for(var i = 0; i < 5; i++)
{
dataString +="<li><a href='#' rel='"+i+"' title='"+i+"'
class='group'>"+i+"</a></li>"
};
$('#subs').append(dataString);
// the list is visible, now attach click event
    $("a").filter(".group").click(function() {
        alert(this.getAttribute('rel'));
        });
why the alert(this.getAttribute('rel')) is never executed ?
please advise.
