Custom Field doesn't get saved in database

I am using custom field to display textarea with JCE editor. Editor is displayed correctly but after I hit submit, content of custom field is not stored into db. I have created columns with custom field names. This is the code:

<?php
$editor = JFactory::getEditor();
echo $editor->display( 'text_4', $form->data("text_4"), '80%', '200', '75', '10', false); 
?>

and I created column with name text_4 for that field. But it store nothing. I am seeing this code in code editor.

<div class="form-group gcore-form-row" id="form-row-custom3"><label for="custom3" class="control-label gcore-label-left">Hoe wordt uitgezocht wat je hebt?</label>
<div class="gcore-input gcore-display-table" id="fin-custom3"><?php
$editor = JFactory::getEditor();
echo $editor->display( 'text_4', $form->data("text_4"), '80%', '200', '75', '10', false); 
?></div></div>

thanks for your help

Hi bveljkovic,

Please drag a Debugger action into the On Submit event, then submit the form and post the debug - including the 'dummy emails' results here.

Note: if you are using the Easy Wizard you can turn on Debug on the Others tab in CFv4 or the Setup tab in CFv5.
