why is rohan's name changed..

guys i found out that rohan 's name is actually navtej sahni but onscreen means in the serials b it antariksh or kesar its written navtej singh...😳

i'm confused

does anyone have any idea to help me.. 😳

maybe he just wishes to write his name that way due to some numerology or astrology reasons 😉
