ui 1.7 dialog problem


Since i've upgrade to 1.7 , the dialogs (all working with 1.5.3) only
works first time. If i close and try to reopen , nothing happens.
code sample:
<script type="text/javascript">
$(document).ready(function() {
$('#solic<%=request("cod_casa")%>').click(function() {
    $('#divdt<%=request("cod_casa")%>').html('<center><img src="/images/
ajax-loader.gif"></center>').load('data_pers.asp',
    {
    cod_casa: '<%=request("cod_casa")%>'
    }).dialog({modal: true, width: 500, title: 'Pedido disponibilidade',
                buttons: { 'Fechar': function() { $(this).dialog('close');}}
});
});
</script>
