I think the problem lies in the '.js.erb'. Write javascript in separate javascript files (in app/assets/javascripts/) and use JSON to get data from the rails backend. Have you seen this? http://todomvc.com/ http://todomvc.com/ You can try implementing a backend in Rails for the jquery example. https://github.com/tastejs/todomvc/tree/gh-pages/examples/jquery https://github.com/tastejs/todomvc/tree/gh-pages/examples/jq.... The JS file shows how to organize javascript code - https://github.com/tastejs/todomvc/blob/gh-pages/examples/jquery/js/app.js https://github.com/tastejs/todomvc/blob/gh-pages/examples/jq... Also unless you really like coffeescript, stick with javascript. If the syntax is bothering you, you can write in ES6 (next version of javascript) which has nicer syntax and use babel to convert to ES5 1. https://gist.github.com/danielgtaylor/0b60c2ed1f069f118562 https://gist.github.com/danielgtaylor/0b60c2ed1f069f118562 2. http://justicen.com/#/posts/74046fea9a4c61477db9 http://justicen.com/#/posts/74046fea9a4c61477db9
