Salman Khan Thursday unveiled the trailer of his much-awaited film "Jai Ho" at Chandan cinema in the presence of media and his fans. When asked why was the title changed from "Mental" to "Jai Ho", he said: "'Mental' was a working title and if at all we had gone ahead with 'Mental', maybe people have stated calling us as Mental Khan... I don't have a problem but the other Khans may not like it. Besides my father didn't like the title 'Mental' and we must listen to our father... 'Jai Ho' was also suggested by my father."  Show less
