Custom widgets are registered in toolbar automatically.
The plunker you've provided (it's our sample) looks ok for me.
Please provide a working sample illustrating your issue.

SurveyCreator uses survey-knockout library

I've updated your sample - https://repl.it/repls/InferiorSeparateRobot

import * as SurveyKo from "survey-knockout";
import init from './widget';
init(SurveyKo);
