help me

[FiGo]

addCommandHandler("criminal", function (player) exports.GTIhud:dm("This command has been disabled, you must commit a crime to join in Criminals team", player, 255, 0, 0) end )

function isCriminal(player)
    if (exports.GTIteams:isPlayerInTeam(player, "Criminals")) then return false end
    if (exports.GTIbusiness:setPlayerCriminal(player) ~= "Criminal") then return false end
    return true
end

what is wrong in that function why when I commit a crime it doesn't move me to the criminal team
