Javascript events not loading

None of the bootstrap javascript events (in this case the ones for collapse / expand) will bind to my elements. I'm new to bootstrap so maybe there is a problem somewhere ????

When pasted into bootply, it works fine http://www.bootply.com/tMvXXUvlz6

a limited release live example of a broken version is also available here http://quirell.ngrok.io/tagged/life#

edits:

Nothing is displayed on the console showing any error message. I just noticed that there is a line at the top of bootstrap which is throwing an error as there is no jQuery and I cannot get this line to run (by removing jQuery).

I had a feeling that all the js are broken, so I did console.log('pizza')

right under the bootstrap.js call and it worked fine. It's as if my page has never applied bootstrap.js content ??????
