Why is checkbox value reset on change event and ajax submit?

Question

JavaScript

Good day.
I implement sending ajax request when clicking on the checkbox

<div id="div-pay">
    <div class="deliveri-block">
      <div id="deliveri-list">
      <? foreach ($arResult['DELIVERY_LIST'] as $arDelivery):?>
          <label>
              <input type="radio" name="delivery_id" class="deliveri-el"
                     value="<?= $arDelivery['ID'] ?>">
              <?= $arDelivery['NAME'] ?>,
              <?= $arDelivery['PRICE_DISPLAY'] ?>
          </label>
          <br>
      <? endforeach; ?>
      </div>
    </div>
   
   <div class="payment-block">
      <div id="payment-list">
      <? foreach ($arResult['PAY_SYSTEM_LIST'] as $arPaySystem): ?>
          <label>
              <input type="radio" name="pay_system_id"
                     value="<?= $arPaySystem['ID'] ?>"
                  <?= $arPaySystem['CHECKED'] ? 'checked' : '' ?>>
              <?= $arPaySystem['NAME'] ?>
          </label>
          <br>
      <? endforeach; ?>
    </div>
  </div>
</div>

checkboxes = Array.from(document.querySelectorAll('.deliveri-el'));
checkboxes.forEach(function(checkbox, i) {

    checkbox.onchange = function() {

        $.ajax({
            url: BX.message('TEMPLATE_PATH') + "/ajax.php",
            type: 'POST',
            data: {
                settings: this.name,
                id: this.value,
                checked: this.checked ? 1:0,
                delivery_id: $(this).val()
            },
            beforeSend: function() { checkbox.disabled = true; },
            complete: function() { checkbox.disabled = false; },
            success: function(response) {
               $('#payment-list').html(response);
            }
        });
    }
});

I tried in many ways, but in all cases, after ajax renders the response, the checkbox ceases to be checked.
It looks something like

this after I clicked on one of the deliveries..
Please tell me.

UPD. In general, the error disappeared as soon as I changed the name attribute to another one. Although the previous ANYWHERE is no longer involved. what was the mistake. Thanks for the advice.
