closeEvent gets called for each popover instance when pressing Esc

Hey - first: great plugin! So far the best jQuery popover plugin I've found.

The issue I am facing is this: I'm trying to set focus to the button element after the popover is closed.
I have tried two different ways of doing this:

$(".popover-control1").popover({
    content : "#content1",
    closeEvent: function(btn) { btn.focus(); }
});
$(".popover-control2").popover({
    content : "#content2",
    closeEvent: function(btn) { btn.focus(); }
});

and

$(".popover-control1").popover({
                        content : "#content1"
}).bind('hidePopover', function() { $(this).focus(); });
$(".popover-control2").popover({
                        content : "#content2"
}).bind('hidePopover', function() { $(this).focus(); });

However, when I close the first popover, the focus is set to .popover-control2, nit .popover-control1 - in both cases.

The problem is that - in both cases, the closeEvent and 'hidePopover' are triggered for each popover instance, and thus - the focus is set to the last popover's button.

As far as I understand this is caused only when I press "Esc" on the keyboard to close the popover.

Okay, here's a solution I came up with - any comments/ideas welcome.

Replace line 275 with this:

                if ($.fn.popover.openedPopup != null)
                    $.fn.popover.openedPopup.trigger('hidePopover');
