title: Knockout render checkboxes using foreach
body: <p>it is my firs experience with <code>knockout</code>. I cannot find how to render list of checkboxes using <code>foreach</code>.</p>
  
  <p>what I tried: </p>
  
  <pre><code>&lt;div class="col-sm-12" data-bind="foreach: placeCategories"&gt;
      &lt;label class="col-sm-6" data-bind="text: name"&gt;
           &lt;input type="checkbox" data-bind="value: val"&gt;
      &lt;/label&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>But I get only name, without check box. Probably label inner html is overwritten. But how to show also check box and text both?</p>
