Update the Formula not refreshing the page

Update the Formula not refreshing the page

Goal:
WHen you press on the feedback button, you add som data in the formula and then you send it away. In the last approach, you retrieve a feedback message "Thank you for your feedback!"

Problem:
How should it changed from Feedback formula to the feedback info "Thank you for your feedback!" in the same page without refreshing the webpage.

What technology do you need to use in order to achieve the goal? I was thinking about json, angular etc.

You update and not refreshing the page.

Info:
I'm using asp.net mvc.

Thank you!
