close option for dynamically added AJAX tab is not working

close option for dynamically added AJAX tab is not working

I am adding ajax tabs using add method (with close span). But $('.ui-icon-close').live('click', function() {}) doesn't seems to get triggered.

  <link type="text/css" href="js/jquery/jquery-ui-1.8.custom/css/ui-lightness/jquery-ui-1.8.custom.css" rel="stylesheet" />
 
  <script type="text/javascript" src="js/jquery/jquery-ui-1.8.custom/js/jquery-1.4.2.min.js"></script> 
  <script type="text/javascript" src="js/jquery/jquery-ui-1.8.custom/js/jquery-ui-1.8.custom.min.js"></script> 
 
  <style type="text/css">
    #tabs { margin-top: 1em; }
    #tabs li .ui-icon-close { float: left; margin: 0.4em 0.2em 0 0; cursor: pointer; }
    #add_tab { cursor: pointer; }
  </style>
 
  <script type="text/javascript">
 
  $(function() {
     var tab_counter = 0;

 
    var $tabs = $('#tabs').tabs({
      ajaxOptions: {
      error: function(xhr, status, index, anchor) {
        $(anchor.hash).html("Couldn't load this tab.");
      }
    }
    ,add: function(event, ui) {
     
     //select newely opened tab
      $(this).tabs('select',ui.index);
    } 
    });

    // actual addTab function: adds new tab using the title input from the form above
    function addTab() {
      var id = ""+tab_counter;
      var removeTabSpan = '<span id="span-'+id+'" class="ui-icon ui-icon-close">Remove Tab</span>';
     
      var tab_title = 'A New Tab '+id;
      // tab that loads remote file contents
        $("#tabs").tabs("add", "metering/grid/newtab.jsf" + '?' + id,  tab_title+removeTabSpan);
        tab_counter++;
     
    }

    // addTab button:
    $('#add_tab')
      .button()
      .click(function() {
        addTab();
      });

    // close icon: removing the tab on click
    $('.ui-icon-close').live('click', function() {
      var index = $('li',$tabs).index($(this).parent());
      $tabs.tabs('remove', index);
    });
  });
  </script>
