How to utilize the browser back button with AJAX requested dynamic content

Question

I have asked a question like this before, and the answer was great but the more I looked at my code the more confused I got, and after 10hrs my brain is shot and I'm in need of help. So all my content is loaded dynamically via Jquery's $.post and loaded into #content-container. Now I included my entire Jquery file to show you why I am getting so confused as how to get this to work without re-writing all the code. As you can see, and what I'm thinking, is that the history plugins such as BBQ, and history.js seem to be out of the question because I don't use anchor tags and the multitude of .live('click', funcition() { I have use different classes and id's for various reasons. I also believe that rules out using the hash and linking it to a single class via .trigger(), executing the AJAX(hope that makes sense). The only option I have left is actually kinda my question. Would it be possible to load the dynamic content into #content-container still using the $.post with $.load() or window.location and actually have the previous content loaded when the browser back button is clicked.

I greatly appreciate the help, really.....

Use history.js to pushState and then window.history.back()
