Little Lua help

[Parach]

I've been messing around in lua recently, making basic UI mods and such. Bear in mind i'm no lua or programming expert, and as such my knowledge is limited. Anyway, i was playing around with position of monk chi bar on default blizzard UI. Since in legion chi will only be available to WW monks I figured i should use Specialization condition for that. Here is my code:

local _, Class = UnitClass("player") -- getting the player class

local spec_id = GetSpecialization() -- getting spec info

if Class == "MONK" then
	if spec_id == 1 then --this is for brm stagger bar
		MonkStaggerBar:ClearAllPoints();
		MonkStaggerBar:SetPoint("CENTER",ParrentUI, "CENTER", 0, -185); 
		MonkStaggerBar.SetPoint = function() end
		MonkStaggerBar.LeftText:SetAlpha(0);
		MonkStaggerBar.RightText:SetAlpha(0);
	elseif spec_id == 3 then --this is for ww chi bar
		MonkHarmonyBarFrame:ClearAllPoints();
		MonkHarmonyBarFrame:SetPoint("CENTER",ParrentUI, "CENTER", 0, -185); 
		MonkHarmonyBarFrame.SetPoint = function() end
	end
end

The problem is when I log in game frame doesn't move. When I do /reload it works perfectly. My guess is that GetSpecialization() function is called before game can even read what my spec is. I also tried printing value of "spec_id" after i grab it with GetSpecialization() function and got the same problem. "nil" when I log in, and value after reload.

If anyone can help me fix this that would be great.

local function Setup(self, event)
  -- your code
end

local events = CreateFrame('Frame')
events:RegisterEvent('PLAYER_LOGIN')
events:RegisterEvent('PLAYER_SPECIALIZATION_CHANGED')
events:SetScript('OnEvent', Setup)
