[jQuery] Problem with animate callback

Hi,

I have function which animates div#square and insert link in this div
(via animate callback):

function resizeSquare() {
var $square = $('#square');

$square.animate({ width: "300px", marginLeft: "-150px"}, 800)
.animate({ height: "400px", marginTop: "-200px"}, 800, function() {
$(this).html('<a href="#" class="clicked">clicked</a>');
});
}

and then I want to display alert after click on this inserted link.
This is a function doing this:

function showAlert() {
$('a.clicked').click(function() {
alert("Display me!");

return false;
});
}

Unfortunately it doesn't work. If I insert this link outside animate
callback it's ok.

Anyone can help?

With regards,
