我使用django-forms-dynamic包和htmx在MultipleChoiceField上动态加载可用选项。这些选项基于日期字段，我使用Amsul的pickadate.js。
我更新了代码。因此，初始查询从数据库中获得正确的选择。但是，如果更改了日期，则不会激发“change”事件。另外，我尝试手动触发htmx事件。没有成功

reservation_form.html

<div class="col-lg-6">
  <div class="form-floating">
    {% render_field reservation_form.date class="datepicker form-control mb-3" 
           hx-get="/reservation/filter-seats" 
           hx-include="#id_dinner" 
           hx-trigger="click change" 
           hx-target="#id_seat_reservation" 
    %}
    <label for="id_date">Dinner Date</label>
  </div>

  <div class="form-floating">
    {% render_field reservation_form.amount_guests class+="form-control" placeholder="" %}
    <label for="id_amount_guests">Guests</label>
  </div>

  <div class="visually-hidden">
    {% render_field reservation_form.dinner %}
  </div>

  <div class="form-check">
    {% render_field reservation_form.seat_reservation class+="form-select" %}
    <label for="id_seat_reservation">Select Seats</label>
  </div>
</div>

pickadate脚本

<script>
    var $input = $('.datepicker').pickadate({
                        format: 'yyyy-mm-dd',
                        formatSubmit: 'yyyy-mm-dd',
                        min: 0,
                        max: 90,
                        disable: {{ blocked_dates }},
                        firstDay: 1,

                        onOpen: function() {
                            // Get the hidden input field
                            var hiddenInput = $(this.$node).siblings('[name="date_submit"]');
                            // Add HTMX attributes to the hidden input field
                            hiddenInput.attr('hx-trigger', 'change');
                            hiddenInput.attr('hx-get', "{% url 'filter-seats' %}");
                            hiddenInput.attr('hx-target', '#modal-xl');
                        }
    });

    $input.on('change', function() {
        var hiddenInput = $(this).siblings('[name="date_submit"]');
        hiddenInput.val($(this).val());
        htmx.trigger(hiddenInput[0], 'change');
    });
</script>

我错过了什么？
