Help regarding .load function in jquery 1.4.1

Got this problem
$('#result').load('ajax/test.html', function() {
 // when calling $('#result').html(), it is always null
 // but when using document.getbyid innerHTML , there is something inside.
});

The null thing never happened on the previous version. Can someone help me on a work around? Thanks
