[jQuery] different lengths by IE and ff

[CreativeMind]

Hi,
I have a dropdown which diplays a companyname with 4 hidden inputs.
these hidden input values are set in text boxes on selected index
change of dropdown.
like this
  var sourcedropdown = $(e.target).parent().parent().children(":nth-
child(7)").children().eq(0);
   $(sourcedropdown).append($('<option></option>').val(val).html
(sourcename).addClass('selectedval'+val));
   var priceval=text[1];
   $.each(priceval,function(leftval,rightval){

   $(sourcedropdown).append($('<input type="hidden" id="hid'+leftval
+' />').val(rightval));

                            });


but when i change the selected value in dropdown, I expect 4 as the
length of inputs, firefox shows 4 in alert but IE shows zero.

var sourcedd=$(e.target).parent().parent().children(":nth-child
(7)").children().eq(0);
 $(sourcedd).change(function(){


                    var hiddenchildrens=$(this).children
("input:hidden");
                   alert(hiddenchildrens.length);
});
}
should i append the hidden inputs in some other way ?

thanx,
