Changing Player Camera Mode on Death?

I have it were when you click a button it changes your camera mode but when you die i want it to reset the camera mode to free i have the script here which works in Studio but not in-game its a normal script in serverscriptservice and localscripts don't work!

game:GetService('Players').PlayerAdded:connect(function(player)
    player.CharacterAdded:connect(function(character)
        character:WaitForChild("Humanoid").Died:connect(function()
        player.CameraMode = 0
        end)
    end)
end)
