Twitter Bootstrap: navbar button not showing or toggling collapse

Question

I'm adapting Twitter's Bootstrap to my Ruby on Rails tutorial project (By Michael Hartl) and the upper navigation isn't collapsing.

I'm currently getting this:

My end goal is this:

I've copied and pasted the start_template.html into mine, ensured that all the right bootstrap.css and js files are referenced, and don't know how else to tackle this issue.

My home.html is pasted below (apologies if it's too much code):

The Bootstrap code seems to work fine.. http://bootply.com/60444

My guess is that something in /assets/custom.css or /assets/application.css is messing up the Bootstrap 'navbar-fixed-top'.

You could try putting 'bootstrap-responsive.css' after those and see if that makes a difference.
