I needed to add required functionality to jQuery.tooltip:

#!python
$("*[title]").tooltip({

    // Bind event handlers on tooltip element (helper.parent = div)
    handler: {click: function(event) { alert(this); } },

    // Comparable to delay: do not hide tooltip immediately.
    // If tooltip is entered during the sticky delay,
    // (after leaving the current element) the timeout stops
    // and is reactivated when leaving the tooltip.
    sticky: 2000}
