title: Button label disappers after disable action
body: <p>This is a very weird problem am facing</p>
  
  <p><strong>HTML:</strong></p>
  
  <pre><code>&lt;input type="button" id="buttonobj" class="some class" value ="Button Name"/&gt;
  </code></pre>
  
  <p><strong>jQuery:</strong></p>
  
  <pre><code>$(function(){
  
   $buttonObject = $('#buttonObj");
   $buttonObject.button('disable');
  
  });
  </code></pre>
  
  <p>When I run this code and watch the HTML in firebug, am getting</p>
  
  <pre><code>&lt;input type="button" id=buttonobj" class="some class" value =""/&gt;
  </code></pre>
  
  <p>The value vanishes.</p>
  
  <p>What does the disable do here. how can it change the value. Is it possible for a css to change a button value??</p>
  
  <p>Am Using jQuery-ui</p>
