I need to create a special input type in adminhtml product form. My input will display as a table but save data as a standard text input.

Following the module Edge ProductAttachments I've created the module for magento 1.

Now a I'm trying to convert the module for magento 2, but when create a new product I obtain the error Class inputtable does not exist.

The steps to reproduce the error on an empty magento 2.0.2 installation:

• 
  Stores -> Product-> Add New Attribute
  


• Set Catalog Input Type for Store Owner to Inputtable and Default label to Mytable


• Click Save Attribute
  


• Add the new attribute to Default attribute set


• 
  Product -> Catalog -> Add Product (simple product)

This is my code:

 $this->addClass('input-table');
 return parent::getHtml();
 
 //remove the other code to compact question

<?php
namespace FunTablegridModelCatalogResourceModel;

class Attribute extends MagentoCatalogModelResourceModelAttribute

 protected function _beforeSave(MagentoFrameworkModelAbstractModel $object)

 $object->setBackendType('text');
 $object->setFrontendInputRenderer('tablegrid/attribute_renderer');
 
 return parent::_beforeSave($object);
 

File: Fun/Tablegrid/Observer/AddTableinputAttributeTypeObserver.php

<?php
namespace FunTablegridObserver;
use MagentoFrameworkEventObserverInterface;

class AddTableinputAttributeTypeObserver implements ObserverInterface

 public function execute(MagentoFrameworkEventObserver $observer)
 $response = $observer->getEvent()->getResponse();
 $types = $response->getTypes();
 $types[] = [
 'value' => 'tableinput',
 'label' => __('Tableinput'),
 ];
 $response->setTypes($types);
 return $this;
 

In Fun/Tablegrid/Model/Catalog/ResourceModel/Attribute.php, try:

protected function _beforeSave(MagentoFrameworkModelAbstractModel $object)
 if ($object->getFrontendInput() === 'tableinput')
 $object->setBackendType('text');
 /* Use setData() and specify full class name below */
 $object->setData('frontend_input_renderer', 'EndertechNumericBlockAdminhtmlAttributeNumeric');
 
 return parent::_beforeSave($object);

I have followed same process to create the custom input type and getting below error:
