How to Make Post Custom Column Editable

Question

I have a custom post, and a custom column on that post, but there is no way to actually edit the data in that column for any particular post. I tried a few things, including hooking to the {name}_edit_form action, but couldn't get anything to work. Any idea what I'm doing wrong?

Custom Column Code

Below is the code that is called on the manage_[custom post-type name]_product_columns filter. This works correctly and creates the column, but there's no UI to edit it when I try to edit a custom post of that type.

public static function setCustomProductColumns($columns){
    $columns = [
        'cb' => '<input type="checkbox" />',
        'title' => __('Name'),
        'pack' => __("Pack")
    ];

    return $columns;
}

To edit custom data via the quick edit form you have to add a meta box via the quick_edit_custom_box action hook. Good examples are provided in the documentation. To edit existing values you need to add some Javascript, which is also available in the provided link.
