The pair have combined for 10 goals in the last six games, with Mooney responsible for five of those in his previous two outings alone.
The 28-year-old, who had been regularly employed out of his favoured attacking position, has come under criticism from fans in the past but denies this has contributed to his motivation.
"It's just one of those things. I don't think I'm proving anyone wrong. You just want to prove yourself right really and I knew I would once I played up front," he told the East London Guardian.
"Lisbie is a great foil. He's strong, good in the air and links the play great. I just play off him really and he's the one who gives me the freedom to play. In terms of that it's been really good.
"It's been exciting. Me and Kevin have formed a great partnership. He's got five or six goals and I've got five goals in the last few weeks."
