[jQuery] .html(data) in Select Box Not working


I have this function:
<script language="javascript">
$(document).ready(function()
{
$("#place").change(function()
{
$.post("types.php",{
     local:$('#place').val()
     } ,function(data)
{
$('#types').html(data);
         $('#types').focus();
     });
});
});
</script>
I does work fine on firefox.. but as normal on IE does not load the
result form types.php...
.html(data) is not showing up.
May anybody help me with?
