php - How to enable Select Box when edit button from jquery-tabledit is clicked?

I have a table with a select box and a dropdown box that I want to be disabled by default (for safety purposes). Now, when the edit button from jquery-tabledit is clicked, I want them to be enabled again. How could I achieve so? When clicking on Save, action_user_2.php gets called with [action] => edit, but I need to listen when edit button gets click on the same page so that I can change the select box to "select name='selectbox'" (removing disabled).

<!--User Approval-->
    <td>
        <form method='POST'>
            if ($row_approved['admin_approved'] == 'Approved') {
            echo "<select disabled name='selectbox' onchange='this.form.submit()'>
                <option value='Approved' selected>Approved</option>
                <option value='Disapproved'>Disapproved</option>
            </select>";
            } else if ($row_approved['admin_approved'] == 'Disapproved') {
            echo "<select name='selectbox' onchange='this.form.submit()'>
                <option value='Approved'>Approved</option>
                <option value='Disapproved' selected>Disapproved</option>
            </select>";
            }
            echo "
        </form>
    </td>

    <!--User Roles-->
    <td>
    <form method='POST'>
    <select disabled class='roles_checkbox' multiple='multiple' name="roles_checkbox[]"
            onchange='this.form.submit()'>
    </select>
<?php
echo "
    </form>
    </td>

<script>
    $(document).ready(function () {
        $('#editable_table').Tabledit({

            // when click on save; action_user_2.php gets called
            url: 'action_user_2.php', // where data will be sent
            
            data: {approved_status: approved_status},
            columns: {
                identifier: [0, "user_id"],
                editable: [[1, 'first_name'],
                    [2, 'last_name'],
                    [3, 'email']]
            },
            // hide the column that has the identifier
            hideIdentifier: true,

            // activate focus on first input of a row when click in save button
            autoFocus: true,

            // activate save button when click on edit button
            saveButton: true,

            restoreButton: false,
            onSuccess: function (data, textStatus, jqXHR) {
                var htmlString = "<?php echo 'User information has been updated'; ?>";
                alert(htmlString);

                // custom action buttons
                if (data.action === 'delete') {
                    $('#' + data.id).remove();
                }
            }
        });

    });
    $('#editable_table').DataTable();
</script>

action_user_2.php

$input = filter_input_array(INPUT_POST);
print_r($input);

console->network->action_user_2.php

Array ( [user_id] => 4 [first_name] => New [last_name] => User [email] => [email protected] [action] => edit )
