I create new extention and add some columns in customer_group table. but i can't get/set custom field.

namespace [NameSpace][Extension]BlockAdminhtmlGroupEdit;

use MagentoCustomerControllerRegistryConstants;
use MagentoTaxModelTaxClassSourceProduct as TaxProduct;

class Form extends MagentoCustomerBlockAdminhtmlGroupEditForm


 protected $_taxProduct;

 public function __construct(
 MagentoBackendBlockTemplateContext $context,
 MagentoFrameworkRegistry $registry,
 MagentoFrameworkDataFormFactory $formFactory,
 MagentoTaxModelTaxClassSourceCustomer $taxCustomer,
 MagentoTaxModelTaxClassSourceProduct $taxProduct,
 MagentoTaxHelperData $taxHelper,
 MagentoCustomerApiGroupRepositoryInterface $groupRepository,
 MagentoCustomerApiDataGroupInterfaceFactory $groupDataFactory,
 array $data = []
 ) 
 $this->_taxCustomer = $taxCustomer;
 $this->_taxProduct = $taxProduct;
 $this->_taxHelper = $taxHelper;
 $this->_groupRepository = $groupRepository;
 $this->groupDataFactory = $groupDataFactory;
 parent::__construct($context, $registry, $formFactory, $taxCustomer, $taxHelper, $groupRepository, $groupDataFactory, $data);
 

 protected function _prepareLayout()
 
 parent::_prepareLayout();
 $form = $this->getForm();
 $groupId = $this->_coreRegistry->registry(RegistryConstants::CURRENT_GROUP_ID);
 /** @var MagentoCustomerApiDataGroupInterface $customerGroup */

 if ($groupId === null) 
 $customerGroup = $this->groupDataFactory->create();
 else 
 $customerGroup = $this->_groupRepository->getById($groupId);
 

 $fieldset = $form->addFieldset('tax_classes', ['legend' => __('Tax Classes')]);

 $fieldset->addField(
 'tax_classes_shipping_tax_class',
 'select',
 [
 'name' => 'tax_classes_shipping_tax_class',
 'label' => __('Tax Class for Shipping'),
 'title' => __('Tax Class for Shipping'),
 'class' => '',
 'required' => false,
 'values' => $this->_taxProduct->toOptionArray(),
 ]
 );

 if($this->_backendSession->getCustomerGroupData()) 
 $form->addValues($this->_backendSession->getCustomerGroupData());
 $this->_backendSession->setCustomerGroupData(null);
 else 
 /* print_r($customerGroup->getData());exit; */
 $form->addValues($customerGroup->getData());
 
 

namespace [NameSpace][Extension]ControllerAdminhtmlGroup;

class Save extends MagentoCustomerControllerAdminhtmlGroupSave
MagentoBackendModelViewResultForward
 */
 public function execute()
 
 $taxClass = (int)$this->getRequest()->getParam('tax_class');

 /** @var MagentoCustomerApiDataGroupInterface $customerGroup */
 $customerGroup = null;
 if ($taxClass) 
 $id = $this->getRequest()->getParam('id');
 $resultRedirect = $this->resultRedirectFactory->create();
 try 
 if ($id !== null) 
 $customerGroup = $this->groupRepository->getById((int)$id);
 else 
 $customerGroup = $this->groupDataFactory->create();
 
 $customerGroupCode = (string)$this->getRequest()->getParam('code');
 if (empty($customerGroupCode)) 
 $customerGroupCode = null;
 

 $customerGroup->setCode($customerGroupCode);
 $customerGroup->setTaxClassId($taxClass);
 $data = $this->getRequest()->getParams();
 $customerGroup->setData('tax_classes_shipping_tax_class',1);
 $this->groupRepository->save($customerGroup);

 $this->messageManager->addSuccess(__('You saved the customer group.'));
 $resultRedirect->setPath('customer/group');
 catch (Exception $e) 
 $this->messageManager->addError($e->getMessage());
 if ($customerGroup != null) 
 $this->storeCustomerGroupDataToSession(
 $this->dataObjectProcessor->buildOutputDataArray(
 $customerGroup,
 'MagentoCustomerApiDataGroupInterface'
 )
 );
 
 $resultRedirect->setPath('customer/group/edit', ['id' => $id]);
 
 return $resultRedirect;
 else 
 return $this->resultForwardFactory->create()->forward('new');
 
 

I try

$customerGroup->getData() or $customerGroup->getCustomField() 

$customerGroup->setData('custom_field',1); 
 $this->_groupRepository->save($customerGroup); 

but fail.

Magento till use Magic setter & getter method for save data of model.

namespace [YourNameSpace];

..... 

use MagentoCustomerApiDataGroupInterface;

...

class [Your_Class] extends [Your_Extend] 
 protected $groupRepository;
 public function __construct( ....
 GroupRepositoryInterface $groupRepository, ......
 ) ..... 
 parent::__construct(
 .....
 $groupRepository,
 .......
 ); 
 $this->groupRepository = $groupRepository;
 

 public function saveCustomfield()
 
 $id = 'Customer_Group_id'; 
 $customerGroup = $this->groupRepository->getById((int)$id);

 $customerGroup->setData('fieldName',$your_Valur);

 $this->groupRepository->save($customerGroup->getCode());
