FancyBox doesn't work if the triggered is dynamically loaded

Hi everyone !

Here is my issue,
I've made a website composed by 9 squares (9 divs)
when i click on a div, an external div is load dynamically on the main page (with "load" method)
Now that i have new divs, i would like these divs to be a link
in order to open a fancybox
In standalone, the fancybox works, but when a integrate it on my website
the fancybox doesn't show, but a new page is displayed

Can someone help me please ?
ps : my website is full jquery and the plugin fancybox is buil with jquery

here is my website : Pixography

here is the standalone version (that works) :  Standalone Version

thanks for help !
Best regards
