Js Doesn't Work When New Content Loaded Into Div / Resolve It?

I'm trying to create a new portfolio website and I've setup the framework the way I'd like to have it. I have some slight animation through the use of jquery, but because I want to preserver that animation availability (on click) I'm needing to do the amateur thing and swap content out in a div - similar to if I were to use an iframe *shudders*.

When you come into the site, you click on a link, and the nav moves up, and the content window opens, displaying the content for the link selected. When you click on the other links, the content simply changes. This all works as of current. The problem is though, once that new content is loaded into the main content display div, the assigned js and/ or jquery does not work.

The page is live, and can be seen here if you click on the 'about' link, it shows the about page, but has all of the information expanded. If you look at the about page directly,[url] it has some light js that allows the headings of the resume to expand and contract - BUT it doesn't work when loaded into the content window. [code]...
