You can't add such an event to an <option>.

You can see that the event doesn't fire in all browsers (the only browsers it works in is < ie11 and Firefox):

$("#trig").click((event) => console.log(event));

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<select>
  <option>default</option>
  <option id="trig">trigger</option>
</select>

The tag does not propagate down any click events. So any click events you try and allocate inside an option will not work. Your best bet is to look at the value you receive in the onChange() callback and then turn on another component which allows the user to enter data. You could even use a window.prompt() to get such data.

You can instead do this:

<select (change)="onChange($event.target.value)">

onChange(val) {
    console.log(val);
    this.edited = false;
}
