Form Block - add help text to form input

Question

I'm trying to add a 'help text' to the questions added by the Form block. Something like this but on the front-end part of the form.

For some reason its not saving the value or getting the value into the edit form. Even when I add it manually to the row it is not in the frontend output.

I made a custom form block / template with the additional changes to:

An extra table column 'helptext' in the db.xml. And updated the block.

<table name="btFormQuestions">
...
  <field name="helptext" type="text">
  <default value=""/>
</field>
...
</table>

An extra field on the editing form (normal and edit):

<div class="form-group">
  <?php echo $form->label('helptext', t('Help Text'))?>
  <?php echo $form->text('helptext', array('maxlength' => '255'))?>
</div>

Output it In the view.php

use \Application\Block\Form\MiniSurvey;
...
<?php  echo $question['helptext']; ?>

Added the extra code to auto.js,

addQuestion:
postStr += '&helptext=' + encodeURIComponent($('#helptext' + mode).val());
...
reloadQuestion:
$('#helptextEdit').val(jsonObj.helptext);
...
resetQuestion:
$('#helptext').val('');

mini-survey.php,

        $dataValues = array(
            intval($values['qsID']),
            trim($values['question']),
            trim($values['helptext']),
            $values['inputType'],
            $values['options'],
            intval($values['position']),
            $width,
            $height,
            intval($values['required']),
            $values['defaultDate'],
            intval($values['msqID']),
        );
        $sql = 'UPDATE btFormQuestions SET questionSetId=?, question=?, helptext=?, inputType=?, options=?, position=?, width=?, height=?, required=?, defaultDate=? WHERE msqID=? AND bID=0';
    } else {
        if (!isset($values['position'])) {
            $values['position'] = 1000;
        }
        if (!intval($values['msqID'])) {
            $values['msqID'] = intval($this->db->fetchColumn("SELECT MAX(msqID) FROM btFormQuestions") + 1);
        }
        $dataValues = array(
            $values['msqID'],
            intval($values['qsID']),
            trim($values['question']),
            trim($values['helptext']),
            $values['inputType'],
            $values['options'],
            intval($values['position']),
            intval($values['width']),
            intval($values['height']),
            intval($values['required']),
            $values['defaultDate'],
        );
        $sql = 'INSERT INTO btFormQuestions (msqID,questionSetId,question,helptext,inputType,options,position,width,height,required,defaultDate) VALUES (?,?,?,?,?,?,?,?,?,?,?)';
        }
$result = $this->db->executeQuery($sql, $dataValues);

Cleared cache and updated the block.

Forum Post on Concrete5 with the changes

---

Solved: Got this working on a clean install of C5.

Small changes:

Added the original files form the concrete/blocks/form to the application folder (and changed the namespace)

db.xml (longtext was unnecessary)

<field name="helptext" type="text" size="65535"></field>

auto.js (Semicolon ; missing in the original concrete/block/form/auto.js (and thus the copy in application))

reloadQuestion: 
$('#editQuestionForm').css('display', 'block');
