Current behavior
Currently, SelectButton only dispatches onChange(). If multiple option is enabled, it is difficult to determine which option was actually clicked on. onClick() would allow for this.

Hello,
Actually onClick() would be unnecessary for select button. As you can see the code which quoted from
PrimeNG-SelectButton page, the options which are clicked on are stored in selectedTypes array.

<h3>Multiple</h3>
<p-selectButton [options]="types" [(ngModel)]="selectedTypes" multiple="multiple"></p-selectButton>
<p>Selected Types: <span *ngFor="let type of selectedTypes">{{type}} </span></p>

However, if you would like to do something with those selected variables, you can add a normal button and use its onClick() event.
