Configuration::get not working

[phpaddicted]

Hi, 

I am using Prestashop 1.6.1.0

I have one field in module for different language, postProcess function is like this :

protected function postProcess()
{

  $languages = Language::getLanguages(false);
  $values = array();
  
  foreach ($languages as $lang)
  {
  	$values['CUSTOMPAGECONFIGURATION_HEADING_TEXT'][$lang['id_lang']] = Tools::getValue('CUSTOMPAGECONFIGURATION_HEADING_TEXT_'.$lang['id_lang']);
  }
  Configuration::updateValue('CUSTOMPAGECONFIGURATION_HEADING_TEXT', $values['CUSTOMPAGECONFIGURATION_HEADING_TEXT'], true);
  return $this->displayConfirmation($this->l('The settings have been updated.'));
}

 

Problem :

When I try to get this configuration variable value in a custom controller( path : /controllers/front/CustomPageController.php ) like shown below, It is not fetching any results:

$headtxt = Configuration::get('CUSTOMPAGECONFIGURATION_HEADING_TEXT');
print_r($headtxt);
exit;

 

It is not printing anything.I want to fetch this value in a controller, But nothing. Can anyone please help me.

 

Thanks in advance.
