Ik krijg nu true of fals terug alleen de remote melding komt niet.
https://jqueryvalidation.org/remote-method/:
The serverside response must be a JSON string that must be "true" for valid elements, and can be "false", undefined, or null for invalid elements, using the default error message. If the serverside response is a string, eg. "That name is already taken, try peter123 instead", this string will be displayed as a custom error message in place of the default.
