Dijit对话框按钮事件未执行

我以编程方式创建了一个Dijit对话框 (jsfiddle)。当Dialog Show被调用时，在运行时传递按钮的id。我试图创建点击事件函数执行在运行时传递的id。

但是事件没有执行。我想知道如何将一个功能附加到对话框按钮。

<button id="show">Show Dialog</button> 

JS

require([
    "dijit/form/CheckBox",

require([
    "dojo/parser",
    "dojo/_base/declare",
    "dojo/domReady!",
    "dojo/ready"],
function (parser, declare, ready, Dialog) {
    parser.parse();
    dojo.ready(function () {
        function showDialog(yesBtnId, noBtnId) {
            var dialog = new dijit.Dialog({
                title: 'Confirmation',
                content: '<table style= "width: 300px;">' +
                    '<tr>' +
                    '<th style="text-align:center; padding: 5px" colspan="2"><label>Are You Sure ?</label></th>' +
                    '</tr>' +
                    '<tr>' +
                    '<td style="text-align:center; padding: 5px"><button id=' + yesBtnId + '>Yes</button></td>' +
                    '<td style="text-align:center;padding: 5px"><button id= ' + noBtnId + '>No</button></td>' +
                    '</tr>' +
                    '</table>'
            });
            dialog.show();
        }
        var myShowBtn = {
            id: "show",
            onClick: function (evt) {
                showDialog('yesDelete', 'noDelete');
            }
        };
        dojo.query("#show").connect("onclick", myShowBtn.onClick);
        var myYesDelete = {
            id: "yesDelete",
            onClick: function (evt) {
                alert('hello its working....');
            }
        };
        dojo.query("#yesDelete").connect("onclick", myYesDelete.onClick);
    });
});
