[jQuery] Problem with animate callback

[dreame4]

Hi,

I have sth like this:

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>');
        });
}

In second animate function I use callback to insert link in
div#square. And everything is ok.
Then I want to display alert after clicking on this link, but nothing
happens. This is function which should display alert:

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

                return false;
        });
}

If I insert this link outside animate callback everything is ok. So,
I'm doing sth wrong or it's jquery bug/behavior?

And I use jQ 1.3.1.

With regards,
