title: Knockout subscribe scope
body: <p>Is there any possibility to change the scope of the subscribe in Knockout?</p>
  
  <p>I have something like this:</p>
  
  <pre><code>element =
      {
          type: ko.observable()
          name: ko.observable()
          content: ko.observable()
      }
  
  element.type.subscribe(this._typeChanged.bind(element))
  </code></pre>
  
  <p>Basically I want to have an access to the object which property I am subscribed to. Binding like in my code does nto work since it binds to the whole VeiwModel and not the object.</p>
