Javascript 渲染主干视图后，Tinymce不再工作

我在使用带有backbone.js的TinyMCE v4时遇到问题。 当我刷新页面时，编辑器工作正常，但当我使用路由器导航时，它不工作

 APP.Views.AddEdit = Backbone.View.extend({
            el:'#addEditHolder',
            initialize: function() {
                _.bindAll(this, 'render', 'saveModel');
                this.listenTo(this.model, 'change', this.render);
                vent.on("model:save", this.saveModel, this);
                this.render();
                this.form = this.$('form');
                this.name = this.form.find('#addedit_name');
                this.description = this.form.find('#addedit_description');
            },
            template: APP.template2( 'addEditTemplate' ),
            render: function() {
                this.$el.html(this.template(this.model.toJSON()));
                tinymce.init({
                    selector: "textarea.richContent",
                    theme: "modern",
                    width: '100%',
                    height: 240
                });
                return this;
            },
            saveModel: function() {
                this.model.save({
                     name:this.name.val(),
                     description:this.description.val()
                },
                {
                    wait: true,
                    patch: true
                });
            }
        });

可能的答案；
