Data Storage Not Working Have Code?

I have this but it does not seem to store any data.

local DataStore = game:GetService("DataStoreService")
local ds = DataStore:GetDataStore("AbilitySaveSystem")
print(ds)

game.Players.PlayerAdded:Connect(function(player)
 print(player.userId)	
 local Power = Instance.new("StringValue",player)
 Power.Name = "Power"
 print(ds:GetAsync(player.userId))
 if ds:GetAsync(player.userId) ~= "None" then
	Power.Value = ds:GetAsync(player.userId)
	print("He had an ability")
else	
 Power.Value = "None"
 print("He had no ability")
end
 ds:SetAsync(player.userId, Power.Value)
 Power.Changed:Connect(function()
  ds:SetAsync(player.userId, Power.Value)
  print("Updated Ability: ".. ds:GetAsync(player.userId))
 end)
end)


game.Players.PlayerRemoving:Connect(function(player)
print("Bye")
 ds:SetAsync(player.userId, player.Power.Value)
 print("Successfuly saved "..player.userID..": "..ds:GetAsync(player.userID))
end)

this is my method of using regular datastores it works pretty well for me

local Data = game:GetService("DataStoreService"):GetDataStore("AbilitySaveSystem")
game.Players.PlayerAdded:Connect(function(player)
	local Power = Instance.new("StringValue") -- i think using instance parent is deprecated so i didnt use it here
	Power.Name = "Power"
	Power.Parent = player
print("Gave "..player.Name.." Power Data")

	local SavedItems = Data:GetAsync(player.UserId) -- userId is Deprecated use UserId
	if SavedItems then
		Power.Value = SavedItems.Power or "None"
		print(player.Name.." had Power data")
	else
		Power.Value = "None"
		print(player.Name.." didn't have Power data")
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	local Saving = {["Power"] = (player.Power).Value;
		}
	Data:SetAsync(player.UserId, Saving)
	print("Saved "..player.Name.."'s Power Data")
end)
