A victory over Ghana on Thursday night will be required for the hosts to continue their U-17 World Cup adventure.
"We believe we can win against Ghana. We will be together and we will fight for this win," Jeakson was quoted as saying by the FIFA website.
"It is not often that I get a chance to score a goal, so I feel very excited. I want to say thanks to my team-mates for giving me a chance to score."
India's glorious moment arrived when Jeakson headed in a perfect Sanjeev Stalin corner in the 82nd minute.

"I was thinking the ball would be coming my way (from the corner), so I was already focused on that ball and I went and headed it into the goal."
Jeakson said India "deserved" a result in their favour.
"It was a nice experience and I felt on cloud nine when I scored the goal, however we tried our best but were unlucky. It is obviously a great feeling to score for my country in a FIFA World Cup but it would have been sweeter had we won the match.
Irrespective of whether India make the knockout stages or not, the midfielder has taken pride in being part of something unprecedented in the country.
"It's the first time that India is competing in a World Cup. Not only me, but all of India is excited for the U-17 World Cup. It's the first time in history, so I am part of history. I'm very happy and very excited."
His joy last night was rather short-lived as Colombia took the lead a minute later and made it 2-1.
Jeakson, a defensive midfielder in the 21-member Indian team, hails from from Haokha Mamang village in Manipur's Thoubal district. His father Konthoujam Deben Singh suffered a stroke in 2015 and had to leave his job with the Manipur police.
His family is now dependent on the meagre income brought by his mother from selling vegetables at the Khwairamband Bazar in Imphal, 25km from her home.
At nearly six feet, he was called unnaturally tall for a boy of that age, according to former coach Nicolai Adam. But his indomitable brought him back into the Indian team for the U-17 World Cup.
He will go down in the Indian sporting history as the one who gave unbridled joy to millions with a strike that will be etched in memory.
