event target not returning correct index value in IE 10 and less

[sagarchand]

Hi,

I'm trying to get the index of the element (relative to its parent) that is being resized like below
$('.myoptions li').resize(function(e) {
var changedRow = $(this).index(),
newHeight = $(this).height();
$('.dynamic-row-height'+changedRow).height(newHeight);
})

This is working gr8 in chrome, FF& IE11. But in IE 10 and less the changedRow is always retured as -1 instead of the actual index value.

Any help would be much appreciated.

Thanks,
