Save Input Values ​​in Child Rows - Data Tables

Question

I have a responsive DataTable in the form. DataTables generate child rows on small devices. In these rows, I have Input controls. And that causes two problems.

First problem: Values ​​from hidden child strings do not fall into the form data.

Second problem: Values ​​disappear after editing these inputs and hiding the line.

Can anyone help me out?

thanks

Update

Simplified tbody to .DataTable ()

<tbody>
    <tr>
        <td>System Architect</td>
        <td>Edinburgh</td>
        <td>61</td>
        <td>
            <input name="1" type="text"/>
        </td>
        <td>
            <input name="2" type="text"/>
        </td>
        <td>
            <input name="3" type="text" value="example"/>
        </td>
    </tr>               
</tbody>

After .DataTable ()

<tbody>    
    <tr role="row" class="odd">
        <td class="sorting_1">System Architect</td>
        <td>Edinburgh</td>
        <td>61</td>
    </tr>
</tbody>

And advanced

<tbody>  
  <tr role="row" class="odd parent">
    <td class="sorting_1">System Architect</td>
    <td>Edinburgh</td>
    <td>61</td>              
  </tr>
  <tr class="child">
    <td class="child" colspan="3">
      <ul data-dtr-index="0">
        <li data-dtr-index="3">
          <span class="dtr-title">Age:</span>
          <span class="dtr-data">
            <input name="1" type="text" style="background-image: ; background-       attachment: scroll; background-position: 100% 50%; background-repeat: no-repeat;">
          </span>
         </li>
         <li data-dtr-index="4">
           <span class="dtr-title">Start date:</span>
           <span class="dtr-data">
             <input name="2" type="text"></span>
         </li>
         <li data-dtr-index="5">
           <span class="dtr-title">Salary:</span>
           <span class="dtr-data">
             <input name="3" type="text" value="example">
           </span>
         </li>
       </ul>
     </td>
  </tr>
</tbody>
