Click handler isn't firing

No reaction at all to the click.

I'm using Chrome: Version 69.0.3497.100 (Official Build) (64-bit)

app.component.html:

<h2 (click)="chageEmoji()">Hello World {{activeEmoji}}</h2>

app.component.ts:

import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    templateUrl: 'app.component.html',
    styleUrls: ['app.component.css']
})
export class AppComponent {
    emoji: string[] = ['😀', '😁', '😂', '🤣'];
    activeEmoji: string;

    changeEmoji() {
        this.activeEmoji = this.emoji[Math.floor(Math.random() * this.emoji.length)];
    }
}

I think you just have to correct the typo in your HTML file (see "chageEmoji" vs the method name in the TS file - "changeEmoji")
