Почему ajax вызывается только при нажатии на первую кнопку?

             if (isset($itm)) { 
 
                foreach ($invent as $row) { 
 
                    $skin_id = $row["id"]; 
                    $skin_img = $row["img"]; 
                    $skin_tittle = $row["tittle"]; 
                    $skin_name = $row["name"]; 
                    $skin_cost = $row["cost"]; 
 
            ?> 
                    <div class="menu__skins-items"> 
                        <div class="menu__skins-img_box"> 
                            <img src="https://" width="-1" height="-1" alt = "false|false"/>"> 
                        </div> 
                        <input type="button" id="sell" class="menu__skins-sell" value="Продать"> 
                        <input type="button" id="remove" class="menu__skins-remove" value="Вывести"> 
                    </div> 
                <?php 
                }; 
            } else { ?> 
                <div class="none_skin__box"> 
                    <a class="none_skin__link" href="/index.php">Предметов нет</a> 
                </div> 
            <?php } ?> 

 $("#sell").click(function () { 
  $.ajax({ 
    type: "POST", 
    url: "ajax_profile.php", 
    data: { 
      skin_img: 'Butterfly/Dragon_Glass.webp', 
      skin_cost: '2', 
    }, 
    success: function (result) { 
      $("#menu_skin").html(result); 
    }, 
  }); 
});
