NiHa the writers have changed and have no idea about the background of the story. Radhika always called Dev "Dev babu" in public even after marriage. But in privacy it was KK or "unke". In her unguarded moments and in her heart, she would call him either Dev or KK. One scene when Rohan rudely woke her up when she was waiting for Dev, she had called him "Dev". Prior to her fake wedding to Rohan, she was calling him "Dev" when she was thinking that he would come next morning to meet her and everything would be ok. Radhika had called out Dev's name repeatedly when Rohan shot her. Rohan turned psycho at that moment and was so jealous of Radhika Dev's name that he told her that from that time onwards now she would only be calling Rohan's name as Dev was dead.
So in her heart, she never calls him "Dev babu". In her grief, she would not call him "Dev babu" for sure. But again the writers have no clue about the essence of Dev or Radhika or Kanha. otherwise, we wouldn't have seen Dev not looking for Radhika for two days or putting sindoor on Barkha or accusing Radhika of attempted murder.
