"{Task} create"
被呼叫時，會取得三組參數：
Task
模型、created 的 event 物件，以及
剛新增的
Task
物件。這個函式會透過模版產生
Task
清單（以這個範例來說，只會有一
筆資料），並將最終產生出來的 HTML 程式碼，加進網頁元件裡。
不過目前 List 控制器只能針對
Task
模型進行處理。如果能夠讓 List 控制器適用於任何
模型會好得多。因此可以讓控制器多接收一組設定值 model：
$.Controller("List", {
defaults : {
template: "items.ejs",
model: null
}
},{
init : function(){
this.element.html( this.options.template, this.options.model.findAll() );
},
"{model} created" : function(Model, ev, newItem){
this.element.append(this.options.template, [newItem])
}
});
// 建立 Task 清單
$('#tasks').list({model: Task, template: "tasks.ejs"});
融會貫通：開發出抽象化的 CRUD 資料清單
現在我們要改良一下處理資料清單的程式，讓它不僅能在有新資料時，自動在清單裡多
加一筆資料，還要能在資料被修改或刪除時，同步更新資料清單的內容。如果要做 ...
