Kohli was asked to lead the side after regular captain Mahendra Singh Dhoni suffered from cramps while batting and the 24-year-old said it was a good experience.
"I have captained in the IPL but that's a Twenty20 game," Kohli said.
"This was totally unexpected. It was more thinking on the feet. It was a good experience for me.
"I had to keep attacking fields throughout the game because we needed wickets," he added.
"He is someone who's done well for (West Indies). It's a good thing for them. It's good to see a young player from West Indies coming through and play the match-winning knock. We were putting pressure on him and he really stood up," said the Delhi batsman.
Defending the modest total, Indian bowlers did well to trigger a mini collapse, which left the West Indies struggling at 212 for eight after 41 overs.
Kohli then made a surprise decision by bringing in part-timer, Suresh Raina and the offspinner didn't disappoint as he snapped Sunil Narine's wicket in his second over.
However, number 9 batsman Kemar Roach dashed India's hopes as he kept his cool to score 14 crucial runs and take West Indies home.
