[jQuery] show\hide back button

[Boyd]

i have a simple hide the search button and replace it with a loading
graphic script, however on firefox if i hit the back button the
loading image is there not the search button. On IE the search button
is back as expected

 $(document).ready(function(){
   $("#search-form").submit( function() {
    $("#search-button").hide()
         $("#search-loading").show();
   });
 });
