Important for you, if you receive DisplayPath in call back funciton, can be mdlDisplayPath_getElem() function that allows to extract ElementRef (element identification) from DisplayPath.
But in my opinion in the first step it may be better to focus to change tooltip to anything to test the code is working and ignore DisplayPath information temporarily.
