Backbone and JSONP

var Artist = Backbone.Model.extend();

var Artists = Backbone.Collection.extend({
  model : Artist,
  url : "http://api.discogs.com/database/search?type=artist",
  sync : function(method, collection, options) {
    // By setting the dataType to "jsonp", jQuery creates a function
    // and adds it as a callback parameter to the request, e.g.:
    // [url]&callback=jQuery19104472605645155031_1373700330157&q=bananarama
    // If you want another name for the callback, also specify the
    // jsonpCallback option.
    // After this function is called (by the JSONP response), the script tag
    // is removed and the parse method is called, just as it would be
    // when AJAX was used.
    options.dataType = "jsonp";
    return Backbone.sync(method, collection, options);
  },
  parse : function(response) {
