Dlabel.DoClick or intigration doesn't work

[KeithMarex]

So, I've been having some trouble lately with panels and in common; DLabels.
I think it's due to the way the panel is being requested, but my DLabel doesn't work whenever I click on it. No error, it just sits there and does nothing.
Here is my code:

f1menu.lua
surface.CreateFont( "frame", {
    size = 40,
    weight = 100,
    antialias = true,
    shadow = false,
    font = "Segoe UI"
})

local PANEL = {
    Init = function(GLHelp)
        GLHelp:SetSize(900, 500)
        GLHelp:Center()
        GLHelp:SetVisible(true)

        local x, y = GLHelp:GetSize()

        local close = vgui.Create( "DLabel", GLHelp )
        close:SetText("X")
        close:SetFont("frame")
        close:SetSize(65,65)
        close:SetPos(x-50, 0)
        close.Paint = function(w, h)
            close:SetColor( Color(255, 255, 255) )
        end 
        close.DoClick = function()
            GLHelp:SetVisible( false )
        end
end,

 Paint = function(self, w, h)
      -- Blabla
    end
}
vgui.Register("glhelp", PANEL)

cl_init.lua
AddCSLuaFile("f1menu.lua")

net.Receive("f1menu", function()
    if( !glhelp ) then
        glhelp = vgui.Create("glhelp")
        glhelp:SetVisible(false)
    end

    if (glhelp:IsVisible()) then
        glhelp:SetVisible(false)
        gui.EnableScreenClicker(false)
    else
        glhelp:SetVisible(true)
        gui.EnableScreenClicker(true)
    end
end)

Init.lua
AddCSLuaFile("f1menu.lua")

util.AddNetworkString("f1menu")

function GM:ShowHelp(ply)
    net.Start("f1menu")
    net.Send(ply)
end

How do I make it work? Thanks alot already!
