Infinite Scroll with NextGen Gallery

Hi,
Infinite scroll work correctely, but when the Plugin add a post with a nextGen Gallery, javascript functions of Gallery don’t work.

Work only if the post with a NextGen Gallery is the first.

my website with example
http://www.exploratoridelladomenica.it/category/il-diario-di-zia-ste/

wp version 3.4.2
plugin infinte scroll version 2.6.2

Thanks
