Do you see the log from your application? What does uart_callback_set() return? Does it return 0 or something else? If you can see your log, you should see it printed
"uart set callback failure"

If it fails, it will print both lines (with your current implementation):

"uart set callback failure."
"uart set callback finished."

Which one is it? And if it fails, what does it fail with?

Try:

printf("uart set callback failure (err = %d)\n", err_code);
