Hi,
when I updated cell values, success was always false so I had to refresh the page to see the new value. The problem was that the response string "ok" always contained a line brake like
"ok
"
After I replaced
var success = onResponse ? onResponse(response) : (response == "ok" || !isNaN(parseInt(response)));
by
var success = onResponse ? onResponse(response) : (response.includes("ok") || !isNaN(parseInt(response)));
it worked for me.
