Thanks IIya for your suggesion. I tested it in Internet Explorer 6 its working fine.
I think its having the problem when working in internet explorer 9. If you can ckeck the demo application in IE 9 you can find it..
Yup.. in IE9 we will have problems because of old version of prototype and jQuery which has issues there.
simpler workaround without filter - to use meta element which turns IE8 compatibility mode.
