The former Hearts midfielder scored the Gers' second in a 3-2 win at Ibrox.
"I said to Temps after the game that I thought he was absolutely terrific when he went on," he told Rangers' official website.
"He gave us another boost and he obviously scored a great goal and hit the post. [Bilel] Mohsni knocked the rebound in which probably should have counted.
"A real integral part of the win was Templeton going on and we all know he has the ability to change games and win games for us. That again today, after Monday, will do him no harm at all."
