Search in theme not working

I bought techone theme aweek back roughly, at Home layout 1 search was working but somehow at home layout 4 i.e. the current theme for our online store (drakostore.com) is not working. I am also not getting any console error in browser. It seems that event is not firing up at all. Can anybody help me by looking at my online store to tell me why search is not working.
Thanks. Abdul Qayyum
