This worked really well and when data in the tab changes I can add the SAVE icon which fires the function when clicked. But, here's my problem:  I need to know the TAB number which holds the pressed icon.  Bearing in mind that it quite possibly won't be the SELECTED tab.  How can I get the Tab number inside the function?  I also need to keep in mind that some tabs may have been closed which may mess with any saved values.
Any suggestions?
var t = $('#tt');
var p = t.tabs('getSelected');
t.tabs('update', {
  tab: p,
  type: 'header',
  options: {
    iconCls: 'icon-ok',
    tools:[{
      iconCls:'icon-mini-refresh',
      handler: function(){
        alert('SAVE TAB #'+tabNo);
      }
    }]
  }
})
