Why is my backpack/inventory not working properly?

I have been trying to make a custom backpack/inventory Gui that allows players to have a better experience in my game, but it isn't quite working yet. Here is my code:

	local player = game.Players.LocalPlayer
	local character = player.Character
	game.StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Backpack, false)
	function CreateButtons(location)
	    for key, value in pairs(location:GetChildren()) do
	        if value:IsA("Tool") then
	            local ImageButton = Instance.new("ImageButton", script.Parent)
	            ImageButton.Image = value.TextureId
	                ImageButton.MouseButton1Click:connect(function()
	                  character.Humanoid:EquipTool(value)
	               end)
	            end
	    end
	end
	 
	function BackpackRefresh()
	    for key, value in pairs(script.Parent:GetChildren()) do
	       if value:IsA("ImageButton") then
	        value:Destroy()
	       end
	    end
	    CreateButtons(character)
	    CreateButtons(player.Backpack)
	end
	 
	BackpackRefresh()
	player.Backpack.ChildAdded:Connect(BackpackRefresh)
	player.Backpack.ChildRemoved:Connect(BackpackRefresh)
	character.ChildAdded:Connect(BackpackRefresh)
	character.ChildRemoved:Connect(BackpackRefresh)

So, my code basically makes buttons for every tool it finds in a player's inventory/backpack, and it works. But there is only one problem: when the onclicked event is called and the character.Humanoid:EquipTool(value) script runs, the player doesn't have the tool equipped even though the tool has a handle. Is there something I am doing wrong? Tell me please!
