Load content with AJAX using Jquery

We are using the code found in this tutorial [login to view URL] to load content via AJAX using Jquery. The problem is that when you want to load content that uses other script (i.e an image gallery) it is not loaded. The idea is to call the script using getscript function, but for some reason it is not working for us. We are currently using the following Jquery plugins: Scrolling Carousel, Galleriffic, Nivo Slider, Jquery Custom Scroll and the Ajax call itself. Freelancer must found a solution either using the same script in the tutorial or rewriting the whole code. Attached you will find a sample site with all the plugins we are using, and with the proper Ajax calls.
