Javascript 未从主干中的集合中删除对象

这是

我想要实现什么？

我正在尝试使用创建一个消息客户端， 我正处于一个对象从视图中移除的位置

单击“删除”时会发生什么情况？

出于某种原因，remove函数被调用，不会抛出错误，也不会执行任何操作。 我确信这与上的“removedMessage.attributes”有关 removeMessage事件未定义

html

    <!--  BACKBONE TEMPLATE --->
    <div id="messages" style="width: 600px">  
        <form id="addMessage" action="#">
            <div>
                <label for="messageText">Message: </label>
                <input id="messageText" name="message" type="text" />
                <button id="add">Add</button>
            </div>
        </form>
    </div>

   <script type="text/template" id="messageTemplate">
       <button class="delete place-right">delete</button>

       <a class="list autoWidth <% if(has_been_read) { %> selected <% } %>">
           <div class="list-content">
               <img src="//www.polyvore.com/cgi/img-thing?.out=jpg&size=l&tid=20774792" class="icon">
               <div class="data">
                   <span class="item-title-secondary fg-gray"><b><%= sender %></b></span>
               </div>
                    <span class="tertiary-text">
                        <%= message %>
                    </span>
           </div>
       </a>
   </script>

现在可以用了 我将事件附加到集合，这意味着“this”指向整个集合，而不是单个视图

单一消息视图

        var MessageView = Backbone.View.extend({
            tagName: "div",
            className: "listview",
            template: $('#messageTemplate').html(),
            render: function()
            {
                var tmpl = _.template(this.template);
                console.log(this.model);
                this.$el.html(tmpl(this.model.toJSON()));
                return this;
            },
            removeMessage:function () {
                //Delete model
                this.model.destroy();
                //Delete view
                this.remove();
            },
            events:{
                "click .delete": "removeMessage"
            }
        });
