How do I use a code more than once using dynamic pages?

i'm using this tutorial in order to change the content of my pages without refreshing the page. http://ift.tt/1P3HsXU

It's working pretty fine (the pages do change) but, the content I wanna replace is a showcase using this plugin : http://ift.tt/q9Eo6i

When I first load the page, everything works fine but, when I open another page, the content is replace but the code that transform this content into a showcase is not applied so I only have staked images and no showcase.

So, I was wondering if there was any way to trigger the js file without refreshing the whole page.
