title: Adding Jqgrid navButtonAdd icon to the top(cloned) navigator
body: <p>I am using navButtonAdd to have a column chooser in my jqgrid but it adds the button to the bottom navigation bar. Is it possible to add the same icon to the top of my cloned navigation bar. Here is my code...</p>
  
  <pre><code>jQuery("#grid").jqGrid({
           ......
           toppager: true,
           ....
      );  
  
  jQuery("#grid").jqGrid('navGrid','#pager',
      {cloneToTop: true, edit:false, add:false, del:false, search:false},
          { }, { }, { }, { } );
  
  jQuery("#grid").jqGrid('navButtonAdd', '#pager', {
      caption : "",
      buttonicon : "ui-icon-calculator",
      title : "Choose Columns",
      onClickButton : function() {
          jQuery("#grid").jqGrid('columnChooser');
      }
  });
  </code></pre>
