我将创建一个新的类-工具栏与标准操作按钮**（添加，编辑，删除，刷新）**。我写了简单的类：

define([
    "dojo/_base/declare",
    "dijit/_WidgetBase",
    "dijit/_TemplatedMixin",
    "dijit/_WidgetsInTemplateMixin",
    "dijit/Toolbar",
    // Template for new widget
    "dojo/text!/ui/widgets/StandardToolbar.html",
    // Load dijit/form/Button widget as dependency for parsing template
    "dijit/form/Button"
], function(declare, _WidgetBase, _TemplatedMixin, _WidgetsInTemplateMixin, Toolbar, templateString){
    return declare("app.StandardToolbar", [
        _WidgetBase,
        _TemplatedMixin,
        _WidgetsInTemplateMixin,
        Toolbar
    ], {
        templateString: templateString
    });
});

从基本工具栏扩展的模板：

<div class="dijit" role="toolbar" tabIndex="${tabIndex}" data-dojo-attach-point="containerNode">
  <button data-dojo-type="dijit/form/Button" data-dojo-attach-point="addButton">Add</button>
  <button data-dojo-type="dijit/form/Button" data-dojo-attach-point="editButton">Edit</button>
  <button data-dojo-type="dijit/form/Button" data-dojo-attach-point="removeButton">Remove</button>
  <button data-dojo-type="dijit/form/Button" data-dojo-attach-point="refreshButton">Refresh</button>
</div>

而且它不起作用。工具栏中的按钮呈现为标准的HTML按钮，而不是Dojo小部件。我做错了什么？
