gistfile1.js

/* 
*   Not working in IE for some reason
*   it's really just using and Underscore method through Backbone
*/
var fbStreams = this.options.streams.models.filter(function(s){
  return (s.get('selected') == true && s.get('type') == "facebook");
});

/* 
*   THIS works in IE
*   it's the actual Underscore method
*/
var fbStreams = _.filter(this.options.streams.models, function(s){
  return (s.get('selected') == true && s.get('type') == "facebook");
});
