Enabling Lightbox links in GMap popups

My question: Is the following the only solution?

I made a Gmap page with Views that display a lot of places. Every places contains a slideshow (multiple imageField) that I usely display with LightBox2 module. A summary of every node is display inside Gmap little popup when clicking on a marker (normal behavior).
Unfortunality the code inside this popup is dynamicaly inserted so the "Lightbox links" (ie href="image.jpg" rel="light....) aren't effective.

After some research I found that I need to call Lightbox.initList() after the content insertion. So here is what I did:

I modified marker.js from GMap Module (I know it's bad but I really didn't find any better solution to reach the click on marker event) and inserted after marker.marker.openInfoWindowHtml(marker.text); line 64, the following line :

if (marker.text.search('rel="light')) onGmapPopupOpen('Lightbox.initList()',0,5,2000);

and somewhere (I did it in the marker.js file but I guess you can do it whereever you want) (CAREFUL I used some JQuery code) :

function onGmapPopupOpen(action,mytime,step,maxtime) {
    if ($('.gmap-popup').length>0) eval(action);
    else if (mytime<maxtime) setTimeout("onGmapPopupOpen('"+action+"',"+(mytime+step)+","+step+","+maxtime+")",step);
}

Mainly what it does is if the content of the popup to be inserted contains rel="light (that means there some lightbox behaviour) and when a click on a marker is made, it waits for the popup to be displayed before executing the Lightbox.initList() .

I know it's not straight forward, the best way would have been to write a patch to the GMap module to raise an event and then bind Lightbox.initList() to the new event but I really didn't have time to spend on that (nor the knowledge). Maybe someone could do it, I guess it's an interesting event to have (enabling javascript execution after gmap popup loads).

Did I miss something and there's a better solution?

Hope it helps.
