I'm not being able to understand what would "jQuery Object" mean exactly, since I don't use it. But...
I suppose that when referenced upon - these jq., dom objects - are somehow wrapped by it enabling you to use few or more extra methods not available on DOM api, - than the quickest run about might be by setting its "display" property to 'none' and perhaps give it an ID before appending it to the document so you can create a jQ handle for it with a conventional jQuery call as with any other element.
It's a workaround, but might serve you well until some other more direct route is found.
This is, of course - in case that the code from above didn't work for you.
