My custom stick wont recognize triggers in MvsC3


Hello, recently i played Mvsc3 for PS3 with my custom stick ,everything was fine but the game doesnt recognize when i press triggers (R2 and L2), i thought some wire unplugged/unsoldered, so i opened the stick but everything was fine.

i tried the stick on PC and every button test worked fine, then i tried the stick on my PS3 again with SSFIV and it worked flawlessly… so i dont know what is going on.
