Jquery FadeOut table row not working with Internet Explorer

JQuery is write less and do more, we all know that
I have a simple table row and I want to use the fadeOut effect on this row, it is working over all the browsers  except the Internet Explorer "for sure :)"

so I try to find out the problem and whats wrong with Internet Explorer
till I understand this
I have to effect on each child 'cells' of the row before the row it self

var $tr = $(this).parent().parent();

$tr.parent().children().each(function () {
                                $(this).fadeOut('slow');
                            }).fadeOut('slow');
