how to use backbone and jquery validator together

SomeBackboneView.js

var someView = Backbone.View.extend({
        initialize: function(options) {
        },
        events: {
          'keyup .error': 'validateField'
        },
        validateField: function(e){
           $(e.currentTarget).valid();
        },
        render: function(){ 
           //..all your adding to the view here
           this.setValidator();
           return this
        },
        setValidator: function(){
           $("#your-form",this.el).validate()
        }
 });

I just can't understand why you're triggering keyup on .error class. That doesn't make sense, at least for me.
