title: text box value not refreshing
body: <p>I have a text box that has a default value that disappears onfocus:</p>
  
  <pre><code>&lt;input data-role="none" class="search-box" id="addressLookupTxt" type="text" value="City and State or Zipcode" onfocus="clearText(this)" onblur="clearText(this)" /&gt;
  </code></pre>
  
  <p>After entering a text (ie 90210) and submitting the value, when i return to the page with this input, the submitted value is still present.  </p>
  
  <p>How can i refresh this value so its the default when i return?</p>
  
  <pre><code>$('#CheckInPage').live('pagebeforeshow', function(toPage, fromPage){});
  </code></pre>
