Head Coach Martin threw caution to the wind by introducing Robbie Keane from the bench just seconds after Mido had levelled the score at 2-2 after we'd trailed 2-0.
The plan worked to perfection as 15 minutes later as Robbie combined with Jermain Defoe to smash home the winner.
Darren Bent had earlier handed the home side a 2-0 lead before Ledley King reduced arrears after 51 minutes.
"There was something at the back of my mind which told me that we could get something," said Martin.
Sometimes you have to force your luck but you can always say in hindsight that you made the right substitutions
"I thought if we could get a draw it would be a great result but with players like Robbie Keane around you always have a chance. I know if he's in that situation nine times out of 10 he will score.
"We did better in the second half. In the first we started well, created three good chances but then we didn't pressurise the ball a couple of times and they have speedy players, so if you want to play offside you have to do it with all four defenders. At this level, we gave away cheap goals.
"Even at 2-1, I felt we could do something. Mido scored a great equaliser and we could then take a gamble or choose a settled system at the back, but Robbie was on the line and I thought we should go for the gamble. I think on the second half performance we deserved it."
Martin Jol said he was always confident we would get some reward against Charlton after his gamble paid off at the Valley.
