Backbone.Validation.bind(this) causes undefined error in ios simulator

[bmurmistro]

Backbone.Validation.bind(this) causes undefined error in the ios simulator. The error appears to be random... it works fine about 50% of the time. If I run it on my iphone, it works fine... I've never seen the error. FYI, I'm using phonegap, jquery, jquery mobile, parse, and backbone. Here is my code (coffee script):

define ["jquery", "backbone", "models/ProductModel"], ($, Backbone, ProductModel) ->

  # Extends Backbone.View
  SellProductView = Backbone.View.extend(

    # The View Constructor
    initialize: (options) ->
      this.options=options
      Backbone.Validation.bind(this);
      ....
