I have created a custom field for Product Feature in my module override. Custom field for Feature is not saving in the database on edit. But on Add new feature it works fine. Here is the code for my AdminFeaturesController.php file:
<?php
class AdminFeaturesController extends AdminFeaturesControllerCore
