Putting PHP via Ajax to edit input fields

I have a screen of product counts in which is a page with several inputs with values in it, however I am having problems updating the value contained in the input, since it only changes the first line, could anyone help me with that, I've been breaking up with this for a week, thank you.

HTML

<form id="form" method="post" action="">
            <table class="table table-bordered table-striped js-dataTable-full">
              <thead>
                <tr>
                  <th>ID</th>
                  <th>Cód. Produto</th>
                  <th>Descrição</th>
                  <th>Qtd Contada</th>
                  <th>Ação</th>
                </tr>
              </thead>
              <tbody>
                <?php

                if(isset($lista)){
                  foreach($lista->result_array() as $row){ ?>

                      <?php if($row['con_editado'] == 1) {?> <tr style="background-color: #ffff99;"><?php } ?>
                      <?php if($row['con_editado'] == 0) {?> <tr><?php } ?>
                      <td><input type="text" readonly style="border:none;" value="<?php echo $row['con_id']; ?>" name="textId" id="textId"/></td>
                      <td><?php echo $row['pro_cod_pro_cli']; ?></td>
                      <td><?php echo $row['pro_descricao']; ?></td>
                      <td><input type="text" value="<?php echo $row['con_quantidade']; ?>" name="textQtd" id="textQtd"/></td>
                      <td class="text-center"><button class="btn btn-sm btn-primary" type="submit" >Salvar</button></td>
                    </tr>

                  <?php }
                }?>
              </tbody>
            </table>
            </form>

AJAX

<script>
        $(document).ready(function(){
            $("#form").on("submit", function(e){            
              $.ajax({
                url: "<?php echo base_url(); ?>index.php/editarcontagem/updateContagem",
                type: "POST",
                dataType: "html",               
                data: {
                 textId: $('#textId').val(),
                 textQtd: $('#textQtd').val(),

                },
                success: function(data) {
                  $('#textId').html(data);
                  $('#textQtd').html(data);
                }
              });
            });
        }); 
    </script>
