dynamic siblings not found in IE

dynamic siblings not found in IE

Basically I have a table completely generated and appended to the DOM in javascript, I am calling:

$("#tableID" + p).siblings('.child-' + "tableID").fadeOut('fast');

This works fine in FF and Safari, but IE does not find the siblings.

I even did an alert with:

$("#tableID" + p).siblings('.child-' + "tableID").length, and as expected IE returns 0, while FF/Safari return the correct amount (2).

Is this a known issue, and is there a work around?

Thanks in advance.
