jQuery添加的表单行未提交

问：

我正在创建自定义 Worpdress 插件。我有表格。我有按钮，可以将新行添加到表单中，并调用ajax将行添加到数据库中。问题是，如果我添加新行，更改一些输入然后保存它，更改不会传播到数据库。

如果我添加新行，刷新页面，然后进行一些更改并提交表单，它就可以正常工作。

Ajax 调用：

    jQuery(document).ready(function ($) {
        jQuery("#eda-add-new-row").click(function (e) {
            e.preventDefault();
            nonce = jQuery(this).attr("data-nonce");
            jQuery.ajax({
                type: "post",
                dataType: "json",
                context: this,
                url: myAjax.ajaxurl,
                data: {action: "eda_add_row", nonce: nonce},
                success: function (response) {
                    if (response.type == "success") {
                        jQuery("#eda-form-table-body").append(response.like_count);
                        $('#eda-add-new-row .spinner').css('visibility', 'hidden');
                        $('#eda-add-new-row .spinner').css('display', 'none');
                    } else {
                        alert("Někde se stala chyba. Volejte Edu.)");
                    }
                }
            });
        });
});

处理 AJAX 请求的函数：

function eda_add_row() {
    if (!wp_verify_nonce($_REQUEST['nonce'], "my_user_like_nonce")) {
        exit("Woof Woof Woof");
    }

    $result['type'] = "success";
    $result['like_count'] = eda_add_new_row(0,0,0,0,0,0,0,true);

    if (!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
        echo json_encode($result, JSON_HEX_QUOT | JSON_HEX_TAG);
    } else {
        header("Location: " . $_SERVER["HTTP_REFERER"]);
    }
    die();
}

返回新行的 HTML 的函数：

<?php
function eda_add_new_row($row_id=0,$customer_id=0,$brand_id=0,$category_id=0,$product_id=0,$discount=0,$table_order=0,$add_to_db=false,$color='#fff'){

    global $wpdb;

    $row = $wpdb->prefix . 'eda_custom_pricing_users';

    'customer_id'   => $customer_id,
    'brand_id' => $brand_id,
    'category_id'  => $category_id,
    'product_id'  => $product_id,
    'discount'  => $discount,
    'table_order'  => $table_order,
);
$format = array( '%d', '%d', '%d', '%d', '%d', '%d' );
$wpdb->insert( $row, $data, $format );

}
        ob_start();
        $selected = ' selected';

函数，用于初始化插件页面并呈现表格：

                Priorita slev má sestupnou tendenci, tedy pokud např. jeden zákazník má slevu na celou značku a pak slevu na konkrétní produkt, sleva na produkt
                musí být první, sleva na značku jako druhá. Jinak řečeno specifičtější slevy musí být nahoře, všeobecnější níže.
