jquery accordion / change callback

jquery accordion / change callback


*hiya!*
I have a problem with the following script:
------
<script type="text/javascript">
$(document).ready(function(){
$('.dropdown').each(function() {
$(this).accordion({
autoheight: false,
header: 'h2',
change: function(e, ui) {
alert("works");
}
});
});
});
</script>
------
I get no alert, no error message, nothing. I need this callback to
redraw
a shadow on other elements.
The accordion effect basically works. I use jquery-1.3.2 and the
latest jquery.accordion.js.
Any ideas?
tia, bye
