data.src never fires

[PandaWood]

I can't get the autocomplete to populate, I know it's something stupid I must be doing.
Following the demo code, I'm especially wondering why doesn't this code print 'getting data'
You can assume the id is correct, the js/css is loaded and the control looks exactly right, but what does the data.src need to fire?

console.log('starting autcomplete')

const activityList = new autoComplete({
	selector: '#activity-input',
	data: {
		src: async () => {
			console.log('getting data')  // this never runs, no code in here ever runs, what am I missing?
		}
	}
})

I think we need to see more of your code.
