javascript - how to capture the key event from a view ?

I'm trying to capture the key event from a view as follows:

myView = Backbone.View.extend({

  el: $('#someDiv'),
  initialize: function(){
    // initialize some subviews
  },
  render: function(){
    return this;
  },
  events:{
   'keypress #someDiv': 'showKey'
  },
  showKey: function(e){
    console.log(e.keyCode);
  }
})

That does not work ?

ps: There a no [input] elements in the view or its subviews. I just need to know if the user presses any key and then do something on the view.

You can do this in the view initialize() function:

_.bindAll(this, 'on_keypress');
$(document).bind('keypress', this.on_keypress);
