Magento 2 : Label not display after add field with custom type

Question

In admin form, I created custom field type and then, add html content by custom phtml file.

But, after that label not display with custom field type.

Custom Field Type :

$fieldset->addType(
 'custom_field_labels',
 '\Vendor\Magento\Block\Adminhtml\Module\Edit\Renderer\CustomField'
);
$fieldset->addField(
 'custom_text',
 'custom_field_labels',
 [
 'name' => 'custom_text',
 'label' => __('Custom Text'),
 'title' => __('Custom Text'),
 ]
);

Vendor\Magento\Block\Adminhtml\Module\Edit\Renderer\CustomField.php

<?php
namespace Vendor\Magento\Block\Adminhtml\Module\Edit\Renderer;
class CustomField extends \Magento\Framework\Data\Form\Element\AbstractElement {
 protected $_blockFactory;
 public function __construct(
 \Magento\Framework\View\Element\BlockFactory $_blockFactory
 ) {
 $this->_blockFactory = $_blockFactory;
 }
 /**
 * Get the after element html.
 *
 * @return mixed
 */
 public function getElementHtml() {
 $customDiv = $this->_blockFactory
 ->createBlock('Vendor\Magento\Block\Adminhtml\Module\Edit\Tabs\MyTab')
 ->setTemplate('Vendor_Magento::product/tabs/mytabs.phtml')->toHtml();
 return $customDiv;
 }
}

enter image description here

How can I solve that issue?

Any help would be appreciated.

Please check __construct() in this file.

Vendor\Magento\Block\Adminhtml\Module\Edit\Renderer\CustomField.php

<?php
namespace Vendor\Magento\Block\Adminhtml\Module\Edit\Renderer;
class CustomField extends \Magento\Framework\Data\Form\Element\AbstractElement
{
 protected $_blockFactory;
 public function __construct(
 \Magento\Framework\Data\Form\Element\Factory $factoryElement,
 \Magento\Framework\Data\Form\Element\CollectionFactory $factoryCollection,
 Escaper $escaper,
 $data = [],
 \Magento\Framework\View\Element\BlockFactory $_blockFactory
 ) {
 $this->_blockFactory = $_blockFactory;
 parent::__construct($factoryElement, $factoryCollection, $escaper, $data);
 }
 /**
 * Get the after element html.
 *
 * @return mixed
 */
 public function getElementHtml() {
 $customDiv = $this->_blockFactory
 ->createBlock('Vendor\Magento\Block\Adminhtml\Module\Edit\Tabs\MyTab')
 ->setTemplate('Vendor_Magento::product/tabs/mytabs.phtml')->toHtml();
 return $customDiv;
 }
}

This will work :)
