JQuery Datepicker, can't trigger onSelect event manually!

Question

I am using jquery's datepicker where a list of items is populated from an ajax call whenever a date is picked from an inline datepicker object. The script works perfect except that I can't trigger an onSelect event to populate my initial list of items.

I could get around this problem by just populating the list initially using php but I would really like to avoid this.

    $(document).ready(function(){

        //create date pickers
    $("#date_calendar").datepicker(
  { 
        changeMonth: true,
        changeYear: true,
        dateFormat: 'yy-mm-dd',
        defaultDate: $.datepicker.parseDate("y-m-d", $('#date').val()),
        onSelect: function(dateText, inst)
            {
                alert('onSelect triggered! Yay!');
                $('#date').val($.datepicker.formatDate("yy-mm-dd", $('#date_calendar').datepicker('getDate')));

                // Ajax for populating days when selected
                $.post(
                    "server_requests/show_day.php",
                        {
                        date: $('#date').val(),
                        user_id: $('#user_id').val()
                        },
                    function(data)
                    {
                        //return function
                        $('#my_day_tasks').html(data.resultTable);
                    },
                    "json"
                );
            }
    }).disableSelection();

    $("#date_calendar").trigger('onSelect');

});

Any help is appreciated :)

Here is what I came up with and seems to be the best solution:

var inst = $.datepicker._getInst($("#date")[0]);
$.datepicker._get(inst, 'onSelect').apply(inst.input[0], [$("#date").datepicker('getDate'), inst]);

And it works like a charm
