title: Backbone.js views - binding event to element outside of "el"
body: <p>The 2nd answer to <a href="https://stackoverflow.com/questions/7802205/backbone-js-events-binding-like-delegate-in-jquery">this</a> question nicely explains how event declarations in Backbone.js views are scoped to the view's <code>el</code> element.</p>
  
  <p>It seems like a reasonable use case to want to bind an event to an element outside the scope of <code>el</code>, e.g. a button on a different part of the page.</p>
  
  <p>What is the best way of achieving this?</p>
