title: How to update underlying bound KO data after using jQuery to update selected value in <select> drop-down?
body: <p>I'm using jQuery to update the selected value of a data-bound select drop-down
      $(item).val(newVal)
  however, the underlying bound KO data is not updating.  Is there a way to get the bound data to update as well?</p>
  
  <p>The javascript code that is updating the selectedIndex doesn't have knowledge of the data model</p>
