Pull list app not updating
For rich client-side applications, a more structured approach is often helpful.
object.off(null, null, context); // Removes all callbacks on `object`.
Events do not have to be declared before they are bound, and may take passed arguments.
For example: Bind a callback function to an object.
In rich web applications, we still want to provide linkable, bookmarkable, and shareable URLs to meaningful locations within an app.
Use the Router to update the browser URL whenever the user reaches a new "place" in your app that they might want to bookmark or share.
