Substitute Kazenga LuaLua's 85th minute strike was the only goal in the game as Town moved level on points with Charlton and up to 22nd position in the table.
Speaking to BBC Three Counties Radio, Jones was full of pride and didn't hold back with praise for his players.
"You start to think like that but you know you have faith in this group because we have a lot of talent, attacking talent at the end and we were pressing for that winner. Very difficult game, a bit scrapy, no real fluency in it first half, a lot to do with how they play.
"They have played differently to that leading into the game but after the midweek result, we knew something would change. They were very direct, big physical side and we had to match that. We had to win the first ball, get on the second and then dictate the tempo ourselves which is not usually the case being the away team.
"I thought we were solid first half and then second half I thought we were excellent. We upped the tempo, we had probably three or four really good chances to have extended it or won it a bit earlier but look, we will take that all day because any win today would have been magnificent.
"One-nil, away from home, having played the way that we have and having shown the bravery and the composure to come through a real onslaught, I’m so proud of them."
