How to debug AJAX calls
The full answer is spread across the comments on OP’s question but I think this one helped the most:
- Go to the web page which makes the AJAX call
- In Chrome press F12
- Go to the Network tab
- Activate the AJAX call by submitting the form #reservSearch
- In the Network tab look for a call to /Home/GetRates
- Click it
- Check the Preview and Response tabs to see the output from your server
- Is it displaying the expected HTML data which your AJAX call is listening for?
