Dynamically creating jQuery Datepicker using altFields

Question

I dynamically generate a datupik by simply adding an HTML field to the div:

<input type="text" value="" readonly="readonly" name="tier[2][publication_date]" id="publication_date_2" size="10" maxlength="10" tabindex="6" class="publication_date hasDatepicker">
<input type="hidden" name="tier[2][publication_date_db]" id="publication_date_db_2" value="">

Due to the way we store dates, we have a separate altfield for the datepicker that stores our database formatting date selected by the user.

To handle the selection of multiple date sets, I assign a class and use livequery to detect onClicks after the page loads:

$(".publication_date").livequery(function() {
                $(this).datepicker({
                    dateFormat: "dd M yy",
                    changeYear: true,
                    changeMonth: true,
                    onSelect: function(dateText, inst) {
                        console.log(inst);
                    }
                });
            });

I have a problem in how the date picker knows which altfield to fill in? On one datepicker would usually include:

altField: '#start_date_datepicker_altfield', 
altFormat: 'yy-mm-dd',

for the population.

      changeYear: true,
      changeMonth: true,
