 public function generateJsContext(){

Answer 1

I fund the ansver which works

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$model = $objectManager->create('\Namespace\Modulename\Model\Modulename');

but on the oter topic people say that is not recomened and I schould overide _constructor so I did:

public function __construct(

    \Magento\Catalog\Block\Product\Context $context,
    \Magento\Framework\Stdlib\ArrayUtils $arrayUtils,
    \Magento\Catalog\Helper\Product $catalogProduct,
    \Magento\Bundle\Model\Product\PriceFactory $productPrice,
    \Magento\Framework\Json\EncoderInterface $jsonEncoder,
    \Magento\Framework\Locale\FormatInterface $localeFormat,
    \Bachus\BundleContextPros\Model\Bundleset $bundlset, // my class

    array $data = []
) {

    $this->catalogProduct = $catalogProduct;
    $this->productPriceFactory = $productPrice;
    $this->jsonEncoder = $jsonEncoder;
    $this->localeFormat = $localeFormat;
    $this->bundleset = $bundlset; /// My custom model wich i want to load
    parent::__construct(
        $context,
        $arrayUtils,
        $data
    );
}

but I get errors

Fatal error: Uncaught TypeError: Argument 7 passed to Bachus\BundleContextPros\Block\Catalog\Product\View\Type\Bundle::__construct() must be an instance of Bachus\BundleContextPros\Model\Bundleset, array given, called in

Any Idea?
