title: jQuery selector for first text content
body: <p>yes, agree that I should have figured this out from the doc, but no - I could not :-(</p>
  
  <pre><code>&lt;div id="jalla"&gt;
      &lt;span&gt;
          &lt;span class="ui-btn-text"&gt;
              I need this text
              &lt;span class="ui-collapsible-heading-status"&gt;
                  click to collapse contents
              &lt;/span&gt;
          &lt;/span&gt;
      &lt;span&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>How to simply select (and update) the text "I need this text". This is one of the things I've tried:</p>
  
  <pre><code>notWorking = $('.ui-btn-text').text();
  </code></pre>
