Gambhir's catch of bairstow

[CG]

"I haven't spoken about that catch to Dhoni. It just happened in such a quick time I did not realize it. I personally felt that the ball touching the body and grille it is out. Later I came to know it is not out but I did not know it." As per the laws of the game, Bairstow was not out, but he too did not seem to know the rule and walked off thinking he was out though the ball had bounced off Gambhir's hand, hit Bairstow's helmet's grille and dropped back into his hands.

I Believe umpires made a mistake ,But dhoni was well within his rights not to call back the batsman.
