Using AMD for custom jqueryUI widget

ui.customselectmenu.js

/* A small jqueryui widget for extending selectmenu */
(function( factory ) {
  if ( typeof define === "function" && define.amd ) {

    // AMD. Register as an anonymous module.
    define([
      "jquery"
    ], factory );
  } else {
    // Browser globals
    factory( jQuery );
  }
}(function( $ ) {

return $.widget("ui.customselectmenu", $.ui.selectmenu, {
    
  // default options
    options: {
      optionArray: []
    },

    _create: function() {
      this._super();
      console.log(this.element);
    }

  });

}));


/* How to require the custom widget */
    require.config({
      paths: {
        jquery: "/jquery/dist/jquery.min",
        jqueryui: "/jquery-ui/jquery-ui.min",
        customselectmenu: "/ui.customselectmenu"
      },
      shim: {
        customselectmenu: ["jqueryui"],
      }
    }); // end require.config
    require(["jquery","jqueryui", "customselectmenu"], function($, customselectmenu){

      // Test if the widget is loaded using the jquery namespace
      console.log($.ui.customselectmenu);
    });
