You should make this callback a method on the view object and bind the event using Backbone's `events` property, i.e.:

```javascript
events: {
  "click #entry-point-link": "onEntryPointClick"
},

onEntryPointClick: function(e) {
  e.preventDefault();
  window.location.hash = this.entryPoint;
}
```

you'll need to use underscore's `bind` to make sure the `onEntryPointClick` function is bound to the view object.
