How to Insert into with postgresql and JSONB

I am using Postgresql 9.5

I have two tables(product and product_temp) with jsonb colums

I would like to insert the values from product_temp to product

but the name of the data inside the json is not equal ex:

INSERT INTO product(data1->>'__COD__', data1->>'__PAGE__', job_id) 
    SELECT data2->>'cod', data2->>'page', job_id 
         FROM product_temp where  someid = '123'
