Player Model Derma Menu

[hellsgate700]

My friend made a code for me. It's a derma menu that has a selection of player models that you can choose from. When you click on a player model, you become that player model and the menu closes automatically. But when you die or respawn, you change back to your default player model. Is there anyway to stay that player model when you die or respawn? Here is the code:

if SERVER then         concommand.Add( "Set_Model", function( p, c, a )
                if p:Alive() then
                        p:SetModel( "models/player/" .. a[1] .. ".mdl" );
                end;
                if not p.Model then
                        p.Model = p:GetModel();


                end;
        end );
        hook.Add( "PlayerSpawn", "SetPlayerModel", function( p, c, a )
                if p:Alive() then
                        p:SetModel( p.Model );
                end;
        end );
		
	function MyMenu( ply ) --Start the function
		RunConsoleCommand( "model_menu" )
	end --End the function
	
	hook.Add("ShowSpare2", "MyHook", MyMenu) --Add the hook "ShowHelp" so it opens with F1
end


if CLIENT then
        local models = { "swat", "urban", "gasmask", "riot", "leet", "phoenix", "guerilla", "arctic"};
        concommand.Add( "model_menu", function()
                local Menu = vgui.Create( "DFrame" );
                Menu:SetSize( 400, 400 );
                Menu:SetTitle( "Choose a model" );
                Menu:SetDraggable( false );
				Menu:SetVisible( true )
				Menu:MakePopup()
                Menu:Center()
                local List = vgui.Create( "DPanelList", Menu)
                List:SetPos( 5, 20 );
				List:SetSize( 390, 375 )
                List:EnableHorizontal( true )
                List:EnableVerticalScrollbar( true )
                for k, v in pairs( models ) do
                        local Model = vgui.Create( "SpawnIcon" )
                        Model:SetModel( "models/player/".. v .. ".mdl" )
                        Model:SetToolTip( "Models/player/" .. v .. ".mdl" )
                        Model.DoClick = function()
                                RunConsoleCommand( "Set_Model", v )
								Menu:Close()
                        end
                        List:AddItem( Model );
                end;
        end );
		usermessage.Hook("Menu", Menu)
end;

Any help is appreciated.
