如何在requirejs中加载命名模块？

Question

我有一个由requiredJs优化的模块。我想在我的路由器中加载该模块。我能够做到这一点，如果模块没有优化，但优化后，路由器不再工作。以下是优化模块的外观和路由器代码

优化模块：

define('fullpage/pages/participant/ParticipantJoin',[
    'jquery',
    'underscore',
    'backbone',    
    'translator',

    // Using the Require.js text! plugin, we are loaded raw text
    // which will be used as our views primary template
    'text!fullpage/pages/participant/templates/participantJoinTemplate.html',

], function($, _, Backbone, ParticipantInvitation, ParticipantInfo, Translator, template){
    var ParticipantJoinView = Backbone.View.extend({

.... more code

路由器代码

var app_router = new AppRouter;
        app_router.on('route:invite', function(inviteId){


            require([
                'pages/participant/ParticipantJoin'
            ], function(ParticipantJoinView) {

                var participantJoin = new ParticipantJoinView({
                    inviteId: inviteId
                });

            });
        });

错误是ParticipantJoinView为null。我不知道为什么没有加载该模块。如何装载它？

谢谢，
