title: Single select options binding with jQuery validation is not working
body: <p>I am binding a list of objects to a <code>select</code> using knockout. Object Class can have any number of properties</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;select id="TheProperty_City" 
          name="TheProperty_City" 
          class="required" 
          data-bind="options: cityList, 
                     optionsText: 'Name',  
                     value: selectedCity, 
                     optionsCaption: '--select the city--'" /&gt;
  </code></pre>
  
  <p>This works perfectly fine and I can use <code>viewModel.selectedCity().Name</code> or <code>viewModel.selectedCity().Value</code> for loading child elements. </p>
  
  <p>My issue is with jQuery validation. If I leave the statement as above, jQuery does not reset the error even after selection.</p>
  
  <p>I fixed it with by specifying the <code>optionsValue</code> in the bind, but then the <code>selectedCity</code> returns the scalar value and not the entire object. Any idea how to preserve the object behavior or do the validation differently?</p>
  
  <pre class="lang-html prettyprint-override"><code> &lt;select id="TheProperty_City" 
           name="TheProperty_City" 
           class="required" 
           data-bind="options: cityList, 
                      optionsText: 'Name',  
                      optionsValue: 'Value', //added the optionsValue
                      value: selectedCity, 
                      optionsCaption: '--select the city--'" /&gt;
  </code></pre>
  
  <p>The error stays there when <code>optionsValue</code> is not specified:</p>

  <p>Here's my Object Watch on <code>selectedCity</code>:</p>
