Types not extending to subscription handler

[ryardley]

import { EventBus, createEventDefinition } from "ts-bus";

export const fetchJobs = createEventDefinition<{ searchText: string }>()(
  "search_jobs"
);

const bus = new EventBus();

bus.subscribe(fetchJobs, event => {
  // event here is typed as BusEvent<any> and not {type:"search_jobs", payload: {searchText:string}}
});

Not sure how this crept in.
