I also came across this problem when referring to the docs http://javascriptmvc.com/docs/DocumentJS.html
The documentation tells us to create a "crm" folder with a "crm.js" file - it doesn't mention using generators. Incidentally when I used the app generator I didn't get a scripts/docs.js file created. I checked the generators and I couldn't deduce if docs.js was actually created anywhere.
In the end I used your custom docs.js example above - then had to fix a JQuery version issue for the script to finally run successfully.
Just wanted to bring this to your attention =D
P.S. I used the 3.3 zip from the homepage.
