title: kendo observable array sorting
body: <p>I have a observable array in a viewmodel.
  I show the date of array with a template:</p>
  
  <pre><code>&lt;table align="center"&gt;   
    &lt;thead&gt;
      &lt;tr&gt;
        &lt;th&gt;Name&lt;/th&gt;
        &lt;th&gt;Surname&lt;/th&gt;
     &lt;/tr&gt;
    &lt;/thead&gt;
    &lt;tbody data-template="row-template" data-bind="source: client"&gt;&lt;/tbody&gt; 
  &lt;/table&gt;
  </code></pre>
  
  <p>But if i want to sort array? and show the 'client' order by name or surname?</p>
