DataStorage wont save tool once rejoined?

I'm pretty new to scripting so I decided to use an AlvinBlox youtube tutorial to make my own ShopGui. I got to the part of the tutorial where I would make a DataStore that saves my tools that I bought using the shop. However, when I buy an item, I get the item, but once I rejoin it doesn't save. I'm not sure what is wrong with the script or how to fix it. Some help would be greatly appreciated, thanks. API services is on too. Script:

local DataStore = game:GetService("DataStoreService"):GetDataStore("MyDataStorage")

game.Players.PlayerAdded:Connect(function(plr)
	local folder = Instance.new("Folder")
	folder.Name = "leaderstats"
	folder.Parent = plr
	
	local cash = Instance.new("IntValue")
	cash.Name = "Cash"
	cash.Value = 750
	cash.Parent = folder
	
	local data 
	
	local success, errorMessage = pcall(function()
		data = DataStore:GetAsync(plr.UserId)
	end)
	
	if data ~= nil then
		for _, toolName in pairs(data) do
			
			local tool = game.ReplicatedStorage:FindFirstChild(toolName)
			
			if tool then
				local newTool = tool:Clone()
				newTool.Parent = plr.Backpack
				local newTool = tool:Clone()
				newTool.Parent = plr.StarterGear
				
				
			end
		end
	end
	
end)

game.Players.PlayerRemoving:Connect(function(plr)
	local toolsTable = {}
		for _, tool in pairs(plr.Backpack:GetChildren()) do
		if game.ReplicatedStorage.Tools:FindFirstChild(tool.Name) then
			table.insert(toolsTable,tool.Name)
		end
	end
		
	local success, errorMessage = pcall(function()
		DataStore:SetAsync(plr.UserId, toolsTable)
	end)
		

end)


game:BindToClose(function()
	for _, plr in pairs(game.Players:GetPlayers()) do
			local toolsTable = {}
		for _, tool in pairs(plr.Backpack:GetChildren()) do
		if game.ReplicatedStorage.Tools:FindFirstChild(tool.Name) then
			table.insert(toolsTable,tool.Name)
		end
	end
		
	local success, errorMessage = pcall(function()
		DataStore:SetAsync(plr.UserId, toolsTable)
	end)
		
	end
		
end)
