Set Wire output from custom function

[c0baltha1l]

I have made an sENT in lua and have made wire inputs and outputs in the init.lua file. In cl_init.lua I have a derma panel that pops up when you call a custom function (specifically the code activator:SendLua( "loadKeyboard()" ) in the ENT:Use() function in init.lua) and when you press a button it sets one of those outputs to a value. This is the code I have so far inside of my function for that button:

DButton1 = vgui.Create('DButton', DFrame1)
		DButton1:SetSize(40, 40)
		DButton1:SetPos(40, 55)
		DButton1:SetText('1')
		DButton1.DoClick = function()
			Wire_TriggerOutput(self.Entity, "Output 1", 49)
		end

The error I am having is that when I click on the button it yells at me for "calling 'self', a nil value". How would I be able to fix this error?

UPDATE: Just figured it out. Added console commands to init.lua, and also created a variable set to 'self' and used that variable in the wire command which is called by the console command I added earlier.
