Answer 1

You need to provide the model to your controller using the getModel() method. Look in the articles controller of the com_content for example.

Answer 2

You need to add a table file with the publish function within:
defined('_JEXEC') or die;
use Joomla\Utilities\ArrayHelper;
class labTableStructurelist extends JTable
{
/**
* Constructor
*
* #param JDatabase &$db A database connector object
*/
public function __construct(&$db)

parent::__construct('#__ss_structure_tmp', 'id', $db);
}
/**

*
* #param array $array Named array
* #param mixed $ignore Optional array or list of parameters to ignore
*
* #return null|string null is operation was satisfactory, otherwise returns an error
*

*/
public function bind($array, $ignore = '')

$input = JFactory::getApplication()->input;
$task = $input->getString('task', '');

Please note, that this is just an example of a table file, I can't guarantee that this would work just by copy&paste. Please check com_content/table for another example.
Also add a getTable() to your List single item model:
public function getTable($type = 'view_name', $prefix = 'labTable', $config = array())
{
return JTable::getInstance($type, $prefix, $config);
}
Please check if file structure is correct:
List View
structurelist**s** -> list view with multiple items
|-> controller/structurelists.php
|-> models/structurelists.php
|-> view/structurelists/
Single View / List View (publish() for example)
structurelist -> single item view (edit view)
|-> models/structurelist.php (this is important for the publish() in the list view)
|-> models/forms/structurelist.xml
|-> tables/structurelist.php (this is important for the publish() in the list view)
|-> view/structurelist/
