title: Knockoutjs computed passing parameters
body: <p>I am wondering if it is possible with knockoutjs to pass arguments when binding. </p>
  
  <p>I am binding a list of checkboxes and would like to bind to a single computed observable in my viewmodel. In my viewmodel (based on parameter passed to the read function) I want to return true/false based on certain conditions. </p>
  
  <pre><code>var myViewModel=function(){
      this.myprop=ko.computed({read: function(){
      //would like to receive an argument here to do my logic and return based on argument.
  }
  });
  };
  
  &lt;input type="checkbox" data-bind="checked: myprop(someval1)" /&gt;
  &lt;input type="checkbox" data-bind="checked: myprop(someval2)" /&gt;
  &lt;input type="checkbox" data-bind="checked: myprop(someval3)" /&gt;
  </code></pre>
  
  <p>Any suggestions?</p>
