jQuery UI Tabs dynamically adding tabs and content not working

I can't get jQuery UI tabs to work when dynamically adding tabs and content.

<div id="wrap">
    <ul></ul&开发者_StackOverflow中文版gt;
</div>

jQuery

var count = 1;
$('#addspan').click(function() {
    $('#wrap').append('<span id="page' + count + '">testing</span>');
    $('#wrap').find('ul').append('<li><a href="#page' + count + '">' + count + '</a></li>');
    count++;
    $('#wrap').tabs();
});

Check http://jsfiddle.net/qKBUu/1/

You can see that newly created content is not showing in it's respected tabs. All content is showing at once and tabs are not working.

Try this:

    $(function(){
        var count = 1;

        $('#addspan').click(function() {
            $('#wrap').append('<span id="page' + count + '">testing</span>');
            $('#wrap').find('ul').append('<li><a href="#page' + count + '">' + count + '</a></li>');
            count++;
            var selIndex = $( "#wrap" ).tabs( "option", "selected" );
            $('#wrap').tabs("destroy").tabs({selected: selIndex});
        });
    });

Alternative:

Try $().tabs("add", options...)

e.g:

$(function(){
            var count = 1;
            $('#wrap').tabs();
            $('#addspan').click(function() {
                $('#wrap').append('<span id="page' + count + '">testing</span>');
                //$('#wrap').find('ul').append('<li><a href="#page' + count + '">' + count + '</a></li>');
                $('#wrap').tabs("add","#page" + count, count);
                count++;
            });
        });
