  10.       if event.phase == “ended” then
  11.            
  12.             print (“Button “…bid…” was pressed”)
  14.       end
  16. end
  19. for a = 1, #buttonText, 1 do
  21.       local g = display.newGroup()
  23.       local i = display.newRect(g, 0,0,100, 40)
  24.       local t = display.newText(g, buttonText[a],0, 0, native.systemFont, 10)
  26.       g.x = 160
  27.       g.y = a * 48
  28.       g:addEventListener(“touch”,touchButton)
  29.       g.id = a
  30. end

Simply put:

obj:removeEventListener(“touch”,touchButton)

in your event listener when you are ready to remove it.   You could also leave it be and just use a flag to indicate that its disabled and your event listener could check to see if its disabled and simply “return true” if it is.
