Kal Naismith’s double put the Light Blues ahead then won them the game after they had found themselves 2-1 down with just eight minutes remaining.
Gers had actually started brightly but conceded two slack goals and saw their opponents hit the bar in a frantic first quarter hour.
Nevertheless, they dug deep and after Kamil Wiktorski pulled one back, Andy Mitchell levelled then Naismith made sure of a fourth league win in five second-string games so far this season.
Wilson was impressed with the way his team persevered and said: “We were really rattled after losing our early goals but we responded well.
“We’ve got quite a few young players in the team and a couple of them were playing out of position so they took a wee bit of time to settle.
“We got about them at half-time and asked the boys to give us a reaction. We felt the club needed a response to what happened to the first team at the weekend.
“Even though this is the reserve team, we needed to show we want to win games and these boys did that. They’re all fighting for places in the senior side.
“Kenny McDowall was here tonight and he virtually said that to the players at the interval. We’re really delighted with the second-half performance.
“I thought it was going to be one of those nights but we got level and did really well to then go on and take all three points.
“If you’d asked me at 2-0 down with half an hour to go if I’d settle for a draw, I’d certainly have done that.”
In particular, Wilson took note of the way Naismith responded positively to being dropped from the first team at the weekend after he had scored a Scottish Cup winner at Forres Mechanics.
As well as his brace, the youngster had other chances to net and he was a constant thorn in the opposition.
Wilson added: “Kal has got ability, I just don’t tell him that very often because he needs to apply himself. When he does that, you can see the ability he has.
“He needs to work hard in games to allow that to happen and I felt he did that tonight. He has goals in him and those who can bring that to the party will have a chance.”
