United extended their unbeaten run in League One to 11 games after beating Richie Barker’s Dons 2-1, with Stefan Scougall and Billy Sharp netting either side of Darren Potter’s smart equaliser.
And Wilder, whose side sit three points off the division’s automatic promotion places, said: “We asked for a fully committed performance and we got one.
“In games against competitors, you need to come out on top, or get something. “And we have had two games against teams [Bradford and MK Dons] who I still believe will be up there.
“We conceded a goal, it’s not the end of the world. What’s their reaction?
“I thought it was outstanding and we pushed for a winner. Just like last week, we got pegged back and went again. It’s a great quality to have.”
Scougall - recalled to the side in place of Matt Done, who fractured his jaw at Bradford - put United ahead with a scuffed finish in front of the Kop early on.
They suffered a body-blow when former Sheffield Wednesday man Potter drew MK level in the second half before Billy Sharp, five years to the day since his son Luey tragically passed away at just two days old, scored what turned out to be the winner following good work from Scougall.
“When MK got themselves back in the game, they passed the ball really well and opened the game up,” Wilder added.
“They had possession in areas which didn’t really hurt us, but we wanted to get after it. It was a cagey game.
“In that period after they scored, I thought we flicked back into a really good mode, the way we played.”
