一个关于继承实例中监听器不起作用出现的错误，求解答
以下是我学习过程中出现的错误，哪位大神能帮忙下呢，小弟非常感谢啊！代码如下：

JScript code


/*
 * 就地编辑器实例
 */
function EditInPlaceField(id,parent,value){
    this.id = id;
    this.value = value || 'default value';
    this.parentElement = parent;
    this.createElements(this.id);
    this.attachEvents();
}
EditInPlaceField.prototype = {
    createElements : function(id){
        
        this.containerElement = document.createElement("div");
        this.parentElement.appendChild(this.containerElement);
        
        this.staticElement = document.createElement("span");
        this.containerElement.appendChild(this.staticElement);
        this.staticElement.innerHTML = this.value;
        
        this.fieldElemtnt = document.createElement("input");
        this.fieldElemtnt.type = "text";
        this.fieldElemtnt.value = this.value;
        this.containerElement.appendChild(this.fieldElemtnt);
        
        this.saveButton = document.createElement("input");
        this.saveButton.type = "button";
        this.saveButton.value = "Save";
        this.containerElement.appendChild(this.saveButton);
        
        this.cancelButton = document.createElement("input");
        this.cancelButton.type = "button";
        this.cancelButton.value = "Cancel";
        this.containerElement.appendChild(this.cancelButton);
        
        this.convertToText();
    },
    attachEvents : function(){
        var that = this;
        //运行到这里监听事件不起作用了
        addEventListener(this.staticElement,"click",function(){
            that.convertToEditable();
        });
        addEventListener(this.saveButton,"click",function(){
            that.save();
        });
        addEventListener(this.cancelButton,"click",function(){
            that.cancel();
        });
    },
    convertToEditable : function(){
        this.staticElement.style.display = "none";
        this.fieldElemtnt.style.display = "inline";
        this.saveButton.style.display = "inline";
        this.cancelButton.style.display = "inline";
        this.setValue(this.value);
    },
    save : function(){
        this.value = this.getValue();
        var that = this;
        var callback = {
            success : function(){
                that.convertToText();
            },
            failure : function(){
                alert("Error saving value.");
            }
        };
        //ajaxRequest('Get',"url",callback); 
    },
    cancel : function(){
        this.convertToText();
    },
    convertToText : function(){
        this.staticElement.style.display = "inline";
        this.fieldElemtnt.style.display = "block";
        this.saveButton.style.display = "block";
        this.cancelButton.style.display = "block";
        this.setValue(this.value);
    },
    setValue : function(value){
        this.fieldElemtnt.value = value;
        this.staticElement.innerHTML = value;
    },
    getValue : function(){
        return this.fieldElemtnt.value;
    }
}

$(function(){
    var titleClassical = new EditInPlaceField("titleClassical",$("#doc").get(0),"Title Here");
    var currentTitleText = titleClassical.getValue();
})

<body>
    <div id="doc"></div>
</body>

我知道浏览器不同，监听器也是不同的，本想自己总结下的，但是自己这方面还不是很清楚，希望路过的大神能帮忙总结下，真的很感谢哈！

试下直接用jquery的事件绑定？
