Knockoutjs訂閱按鈕點擊？

Question

我試圖從窗體中單擊提交按鈕時調用一個函數。

<div id="myBrowser" data-bind="with: QuestionFilter"> 
<form name="Homeworks" data-bind="submit: searchMeNow"> 
<button data-bind="click: $root.submit, clickBubble: false">Search</button> 

searchMeNow是QuestionFilter函數的內部的功能。我可以用click：binding來調用它嗎？如果沒有，我可以以某種方式訂閱按鈕，如可觀察的？約

這個怎麼樣：

HTML：

<div id="myBrowser" data-bind="with: QuestionFilter"> 
<form name="Homeworks" data-bind="submit: searchMeNow"> 
<button data-bind="click: $root.submit, clickBubble: false">Search</button> 

的JavaScript：

var ViewModel = function(){ 

    function QuestionFilter(){ 
     var self = this; 
     self.searchMeNow = function(){ 
     }; 
    } 

    return{ 
     submit: function(){ 
      alert("Hello world"); 
     }, 
     QuestionFilter:function(){ 
      return new QuestionFilter(); 
     } 
    }; 
}; 
ko.applyBindings(new ViewModel()); 

這裏是全version
