I'm making an admin panel and the player list wont update?

So the gui will list the players in a server but it will not update upon a player leaving/joining unless you rejoin or reset.

any help?

here's the code to update it

local pos = 0
function update()
	pos = 0
	for k,v in pairs(frame.Plays:GetChildren())do
		v:remove()
	end
	local players = game.Players:GetPlayers()
	for i = 1, #players do
		local label = Instance.new("TextLabel",frame.Plays)
		label.Size = UDim2.new(0.425,0,0.04,0)
		label.TextScaled = true
		label.Text = players[i].Name
		label.Position = label.Position + UDim2.new(0,0,pos,0)
		pos = pos +.04
	end
end
game.Players.PlayerAdded:connect(function(player)
	update()repeat wait() until player.Character
	player.Character.Humanoid.Changed:connect(function()
		update()
	end)
end)
game.Players.PlayerRemoving:connect(function()
	update()
end)
update()

Make sure your place isn't a personal place. If it is, then switch it to a normal place.
