Menu getFunc

[Hoft]

I have a problem with simple code ((
My menu allways show only default value!
setFunc works right and changes variable
ZO_SavedVars works right and load/saves variable
When I change variable by menu, key bind, slash command, or any other way and returns to menu… it allways show default value! Where is my mistake?

Addon = {
	name = "Addon",
	Menu = {},
	Vars = {},
	Defaults = {
		["OnOff"] = true,
	}
};

function Addon.Menu()
	local options = {
		{	type	= "header",
			name	= "Options",
			width	= "full"
		},
		{	type	= "checkbox",
			name	= "Enables add-on",
			tooltip	= "",
			getFunc	= function() return Addon.Vars.OnOff end,
			setFunc	= function(value) Addon.Vars.OnOff =value end,
			default	= Addon.Defaults.OnOff,
		},
	local menu = LibStub("LibAddonMenu-2.0")
	local panel = {
		type = "panel",
		name = "Add-on",
		displayName = "Add-on",
		author = "autor",
		version = "1",
	}
	menu:RegisterAddonPanel("AddonMenu", panel)
	menu:RegisterOptionControls("AddonMenu", options)
end

function Addon.OnAddOnLoaded( eventCode, addonName )
	if (addonName ~= Addon.name) then return end

	EVENT_MANAGER:UnregisterForEvent(Addon.name, EVENT_ADD_ON_LOADED)

	Addon.Vars = ZO_SavedVars:NewAccountWide( "Addon_Settings" , version , nil , Addon.Defaults )
	Addon.Menu()
end
