JQuery :: Unable To Call Click Event On Adding Dynamic Html

i have some code as follows

[code]
$(document).ready(function() {
$('a.poplight[href^=#]').click(function() { /do something });
});
[/code]

when i click on a <a> tag with class poplight this works fine. But when i add another anchor tag dynamically to my page (without a page reload, via ajax) like below...

[code]
$('#Table tr:first').before('<tr><td><a href="#?w=700&v=edit&id=23" rel="popup_name" class="poplight" >click here</a></td></tr>');
[/code]

and if i click on that anchor tag that was no placed on top of my first row it does not call the click event instead i can see the variables i tried passing through that anchor tag on my url.

any clue why this is happening.... i donot get any errors as well on firebug.
