# Adding FrontEnd output handlers

In the WebMAP infrastructure, we have output emitters for important events in our components. 

For example:

**.html file**

```html
<wm-button id="button" (click)="clickHandler($event)" [model]="model.button" class="button">
</wm-button>
```

**.ts file**

```typescript
clickHandler(event: any): void {
    // add click handler logic
}
```

The output events are case-sensitive, so make sure you have the correct name.
