You're running into the usual conflict with Turbolinks. Instead of using $(document).ready(...) (jquery) or document.on('dom:loaded', ...) (prototype), you have to listen for a different event in order to start your script:

$(document).on('page:change', ...) replaces $(document).ready(...) in jQuery, and document.on('page:change', ...) does the same in Prototype.

This is all because with Turbolinks, the outermost page loads only once, and never again unless something really disruptive happens to cause a hard reload of the browser. So the usual dom load event only fires once, and any updates to the page don't register with your JavaScript code.
