title: Does keypress events not apply to Backbone.js Views
body: <p>I don't understand if anything is wrong in this idea but the Backbone Views just don't trigger keypress, keyup events. I have created a simple shopping list app is JsBin for you to inspect. In the chrome inspector the <code>ul</code> of the view shows the keyup event but it does not occur when i hit some keys in the keyboard. I need the idea to navigate Treeview using the keyboard events</p>
  <h3>Jsbin</h3>
