Why does this not save when the player leaves?

Hi guys! Any ideas why this doesn't save when the player leaves? I have an OnClose event to keep the game open for another 4 seconds which should be enough to save the data and it doesn't :/

Any help would be appreciated! Thanks :)

I get no errors in the output.

    for _, child in pairs(modelSeven:GetChildren()) do 
        for _, saved in pairs(utility:JSONDecode(tab)) do
            if rawequal(saved.Name, child.Name) then
                child.Value = saved.Value
            end
        end

game.Players.PlayerRemoving:connect(function(plr)
            local tab = {}

            for _, v in pairs(child.Parent:GetChildren()) do
                tab[#tab + 1] = {Name = v.Name, Value = v.Value}
            end

            local encoded = utility:JSONEncode(tab)
            dataStore:SetAsync(plr.userId, encoded)              
        end)
    end

game.OnClose = function()
    wait(4)
end
