@jessepollak You can remove the `helpers = @helpers` if you change `->` to `=>`. 

`@`, in coffeescript refers to `this`.  In this case, the `->` is a callback that changes the scope, so `this` is no longer referring to the controller action.  Using `=>` instead of `->` tells coffee script to work some magic and reset the scope so that `@` still refers to the parent `this`.
