title: How to access $parent or $parents[] in knockout viewmodel click event?
body: <p>I've got a situation where I'd like to notify a grandparent or $parents[1] of a click event that occurs in a sub viewmodel.  So basically I'd like to be able to do this</p>
  
  <pre><code>self.$parents[1].actionTaken
  </code></pre>
  
  <p>I think this doesn't work because of binding context vs viewModel but I'd like to hear if anyone has an ideas on the correct way to do something like this.  Thanks</p>
  
  <pre><code> self.save = function () {
  
       //do stuff to self first, then
  
        self.$parents[1].actionTaken();
  
  };
  </code></pre>
