Hi Aditya,
Please read your question again, and think if it gives enough information for someone who has no clue, what you are working on, to help you.
- How is DataAction1.Response defined
- Screen prints of code that show the problem at hand
- You think data completion should work based on what show why you think that
- Which API response
- What Interface
Your current question only leads to more questions, not answers.
Regards,
Daniel
