secure actionbutton taints again :(

[Rilgamon]

local _,class = UnitClass('player')
local xoffset, yoffset = 8,0
 
local function createBar(bid,id)
    local f = CreateFrame("Frame", "zzABar"..bid, UIParent, "SecureHandlerStateTemplate",id)
    f:SetWidth(1)
    f:SetHeight(1)
    f:SetPoint("CENTER")
    f:SetAttribute('_onstate-page', [[
        print(newstate)
        self:SetAttribute('actionpage', newstate)
        control:ChildUpdate('actionpage', newstate)
    ]])
    if(class == "WARRIOR") then
        print("war")
        RegisterStateDriver(f, "page", "[bonusbar:1] 7;[bonusbar:2] 8;[bonusbar:3] 9;1")
    end
    
    local lastbutton = f
    for i = 1, 12 do
        local b = CreateFrame("CheckButton", "$PARENTActionButton"..i, f, "SecureActionButtonTemplate ActionButtonTemplate",i)
        b:SetWidth(32)
        b:SetHeight(32)
        b:SetPoint("TOPLEFT", lastbutton, "TOPRIGHT", xoffset, yoffset)
        lastbutton = b
        ActionButton_OnLoad(b)
        b:SetAttribute('action--base',i)
        b:SetAttribute('showgrid', 1)
        b:SetAttribute('_childupdate-actionpage', [[
            local offset = (message -1) * 12 + self:GetAttribute('action--base')
            self:SetAttribute('action', self:GetAttribute('action--base'))
            print(message, offset, self:GetAttribute('action--base'))
        ]])
        b:SetScript("OnAttributeChanged",ActionButton_UpdateAction)
        b:SetAttribute('action', i)
 
    end
end

I try to have a bar that switches automaticly. The code above works but I get taints over and over.

4/30 18:55:05.677  An action was blocked in combat because of taint from zz_Actionbuttons - zzABar1ActionButton1:Show()
4/30 18:55:05.677      Interface\FrameXML\ActionButton.lua:246 ActionButton_Update()
4/30 18:55:05.677      Interface\FrameXML\ActionButton.lua:484 ActionButton_OnEvent()
4/30 18:55:05.677      Interface\FrameXML\ActionButton.lua:105

But I have no clue what I should do to make my code secure.
Someone got an easy example how this works ? Looked at BT and Dominos but thats a little above my skills
