Cannot get search events to fire

[trbroyles1]

Describe the bug
Have spent about the last 3 hours banging my head against the wall on this -- really hoping that I'm missing something terribly obvious.

I cannot, for the life of me, get the search event to fire on any type of input that I attach choices.js to. I've tried in FF 77 and Chrome 83. I've tried with Polyfills (even though I shouldn't need them) and without Polyfills. I've tried doing it via JS I have that runs when the page loads, and I've tried setting Choices up directly via the browser console. I've tried with input types text, select-single and select-multiple. The most basic test I've been able to conceive is outlined below...

To Reproduce
Steps to reproduce the behavior:

1. Establish a basic web page with text, select-single or select-multiple control with id "person_first_name" on it.
2. Open the browser console.
3. Run following steps - built by following examples from Github readme.md...

var elmnt = document.getElementById('person_first_name');

var example = new Choices(elmnt, {choices: [{value: 0, label: "Option"}], addItems: true, searchEnabled: true, searchChoices: true});

elmnt.addEventListener(
  'search',
  function(event) {
    alert("search fired!");
    console.log(event.detail.id);
    console.log(event.detail.value);
    console.log(event.detail.label);
    console.log(event.detail.customProperties);
    console.log(event.detail.groupValue);
  },
  false,
);

4. Enter text in the person_first_name textbox

Expected behavior

1. Popup saying "search fired!"
2. Console logging of search events being fired.

Sometimes coming back a day later really does help. I was not using the correct input type. Proposing PR #873 with an amelioration to Readme.md to help others who may encounter similar issues
