Backbone.js：从视图中的另一个方法调用方法？

Question

I am working in Backbone. Working within a View, I would like to call a method from within another method.

events: {
  "click span": "updateURL",
  "click .tag": "clearTag"
},
updateURL: function() { 
   // do stuff
},
clearTag: function(e) {
  console.log(this);
  // this fails
  this.updateURL();
},

But this in clearTag appears to be bound to an element, and updateURL is not being called. Is there a way I can call updateURL from within clearTag ?

From the Backbone source regarding view event bindings:

// Callbacks will be bound to the view, with `this` set properly.
// Uses event delegation for efficiency.
// Omitting the selector binds the event to `this.el`.
// This only works for delegate-able events: not `focus`, `blur`, and
// not `change`, `submit`, and `reset` in Internet Explorer.

The context of this should be your view here, so something else is occurring. Could you provide a fiddle with your source?
