Custom plugin does not save the value

[stydent]

Hi.
My plugin does not save a value after editing a product.
Version VM3 + joomla 3.
Files apply https://yadi.sk/d/a7UD_E-s3QtTtN.

In /administrator/components/com_virtuemart/models/product.php
in the function public function store (&$product){....} all the data comes from.
