Backbone.js: How do you call a View's "method" from outside the View's scope (e.g: inside a model's validation handler)

Question

Basically, I'm trying to do something like this:

Person = Backbone.Model.extend({

   validate: { ... },

   initialize: function(){ 
      this.bind('error', ?......?); <== what do I put?
   },

   // I DON'T WANT TO CALL THIS ONE
   handleError: function(){ }

});


ViewOne = Backbone.View.extend({

   //I WANT TO CALL THIS ONE:
   handleError: function(model, error){ 
         //display inside segmented view using jQuery 
   };

});

I tried options.view.handleError but it doesn't work...

My main purpose: I want a specific View that created the model to handle the error, not have the model to globally handle it all. For example, I want View#1 to do an alert while I want View#2 to display in a div. I don't know if this is the right way of doing it. If not, I would be gladly accept your help.

Thank you.

Since Backbone 0.5.2 it is recommended to drop bindAll in favor of third argument to bind if you need to pass the context.

ViewOne = Backbone.View.extend({
    initialize: function() {            
        this.model.on('error', this.handleError, this);
    },
    handleError: function(model, error) { /* ... */ }
});
...
var person = new Person();
var viewone = new ViewOne({model : person});

General note here is that Models should never know about their Views. Only Views should subscribe to Model events.
