Clickable item links in textbuffer

[CrazyDutchGuy]

I made a textbuffer and i am sending messages to it with :AddMessage(some_msg) If there is an item link in the message, i can't click on it and get a tooltip. If i send the same message to the regular chat window like d(some_msg) then it works. What am i missing to make item links work in textbuffers ?
