I tried it with stacktack.min.js file and did not work. I don't know why it is not working in my case. Might be it is related to the script file placement, as I am adding the script file by append method(if you view the source of my page). However, it is working with local copy of stacktack.js as I mentioned earlier. Anyway, thank you once again.

Using IE8, IE9 and FireFox 3.6.18. I changed the jQuery source in my working demo and it did not work for jQuery 1.6.x
