title: Add text to form label in jQuery
body: <p>I'm trying to add text to a form input on load.</p>
  
  <p>For instance I want to add "(Required)" after "Last Name" in this example:</p>
  
  <pre><code>&lt;div class="agile-group required-control"&gt;
    &lt;label class="agile-label" for="last-name"&gt;Last Name&lt;/label&gt;
  </code></pre>
  
  <p>My attempts are overriding the entire label:</p>
  
  <pre><code>$('.agile-group label').text('test');
  </code></pre>
  
  <p>I'm assuming I need to first capture the existing value and then add to it but no idea how, I'd guess something like this?</p>
  
  <pre><code>var text = $( this ).text();
  $('.form-view label').val( text + "test");
  </code></pre>
