tooltip won't work correctly on ajax-called page?

[arman adhitama]

hi,
i'm not sure whether this is bugs or not, but i can't make tooltip works 
correctly (it won't close on mouseleave) on content loaded with ajax.

here my codes :

$.ajax({
url: $(this).attr('data-popup'),success: function(data) {
$('.content-inner').delay(1000).hideLoading();
$('.content-inner').html(data);
$('*[data-image]').drawingImage();
}
});

$(document).tooltip({
selector: '[title]'
});

checked on my firebug and no error shown.

anyone had experienced same problem with me?

thanks
