Group images in fancybox

I mean images with inline or video in the same gallery or 'group'. I want to do the same thing, this guy did in his solution but his solution is for the old fancybox version. So when a I set a filter on my gallery I change dynamically the data-fancybox-group to make a gallery only between the image that I filter but Fancybox seem to don't like it. So when i switched the filter when I try to click on a images after a filter change the fancybox dosen't work at all.
