can't save data when edit data with modal

why can't save data, when edit data?

index.blade.php

<td>
   <a href="" class="edit_real" data-toggle="modal" data-target="#edit_real-">
        
   </a>
      @include('reals._form')
/td>

                <li class="active"><a href="">Real</a></li>
            </ul>

            <div class="tab-content">
                <div class="chart tab-pane active" id="revenue-chart">
                {!! Form::open([$spent_time, 'url' => route('real.update', $spent_time->id), 'method' => 'POST', 'role'=>'form']) !!}
                 

                <div class="box-body">

                </div>
            </div>
        </div>
    </div>
</div>

this is script in form modal

<script>
// jquery
$('.edit_real').on('click', function (event) {
event.preventDefault();

$('#edit_real').modal();
});
</script>

the data is read when editing, but cannot save to a table like the one in the red line

cannot save to a table like the one in the red line

main point <td> <a href="" class="edit_real" data-toggle="modal" data-target="#edit_real-">
</a> @include('reals._form') </td> where is the mistake?
