Help with textures on frames update

[mich125]

Hi

I have a simple script to change texture on frames, but HP and Mana bars texture gets changed to default when hp/mana value changes.
I assume that I need some sort of "onupdate" script to keep new textures on? Anyone can help me plz?

When i load ui, new textures load fine:



When hp changes, red hp texture is default
When hp/mana changes, mana texture changes to default:

local main = function()
for _, StatusBarTextures in pairs ({
    PlayerFrameHealthBar, 
    PlayerFrameManaBar, 
TargetFrameHealthBar, 
TargetFrameManaBar, 
TargetFrameToTHealthBar, 
TargetFrameToTManaBar, 
    FocusFrameHealthBar, 
    FocusFrameManaBar, 
    FocusFrameToTHealthBar, 
    FocusFrameToTManaBar,
PartyMemberFrame1HealthBar, 
PartyMemberFrame2HealthBar, 
PartyMemberFrame3HealthBar, 
PartyMemberFrame4HealthBar,
    PartyMemberFrame1ManaBar, 
    PartyMemberFrame2ManaBar, 
    PartyMemberFrame3ManaBar, 
    PartyMemberFrame4ManaBar,
CastingBarFrame, 
TargetFrameSpellBar, 
FocusFrameSpellBar, 
        })  do StatusBarTextures:SetStatusBarTexture("Interface\\AddOns\\EVUI\\FrameBackground") end
for _, BarTextures in pairs ({ 
TargetFrameNameBackground, 
FocusFrameNameBackground,
        })  do BarTextures:SetTexture("Interface\\AddOns\\EVUI\\FrameBackground") end
end
 
local ef = CreateFrame("frame")
ef:RegisterEvent("PLAYER_ENTERING_WORLD")
ef:SetScript("OnEvent", function(self)
 main()
 main = nil
 self:UnregisterEvent("PLAYER_ENTERING_WORLD")
 self:SetScript("OnEvent", nil)
end)
