Licode Demo error

I’m getting this error when I run the “https://github.com/lynckia/licode-demos” app.

demoTemplate.js:122 Uncaught TypeError: DEMO.init_demo is not a function at connect_user (demoTemplate.js:122) at HTMLFormElement.document.getElementById.onsubmit (demoTemplate.js:135)

The server is up and running fine, but I’m getting this error when I submit a name on the logon modal form.
