title: jquery autocomplete - noSuggestionNotice doesn't work
body: <p>I am using this plugin: <a href="https://github.com/devbridge/jQuery-Autocomplete" rel="nofollow">https://github.com/devbridge/jQuery-Autocomplete</a></p>
  
  <p>I have added the following in my autocomplete function:</p>
  
  <pre><code> showNoSuggestionNotice: true,
  
   noSuggestionNotice: 'No results found',
  </code></pre>
  
  <p>and the response I get from server side is: </p>
  
  <pre><code> {"suggestions":[]}
  </code></pre>
  
  <p>However, the notice never gets shown. Other things work as expected whenever there are results in the response.</p>
  
  <p>EDIT: my existing code -</p>
  
  <pre><code>  $('&lt;selector&gt;').autocomplete({
      serviceUrl: '&lt;my service url&gt;',
      minChars: 3,
      autoSelectFirst: true,
      showNoSuggestionNotice: true,
      noSuggestionNotice: 'No results found',
      formatResult: function (suggestion, currentValue) {
          &lt;some formatting logic here&gt;
          return resultStr;
      },
      onSelect: function (suggestion) {
          &lt;onSelect logic here&gt;
      }
    });
  </code></pre>
