    </ul>

</div>

this is the REST call

    { id: 1, username: "PersonA"},
    { id: 2, username: "PersonB"}
]

You have to use event handler on anchor tag like this:

<div class="list-group">
    <ul *ngFor="let broker of brokers">
        <li class="broker_list">
            <a (click)="onSelect(broker)" href="#" class="list-group-item list-group-item-action" style="text-align: center;"> {{ broker.username }}</a>
        </li> 
    </ul>

</div>

Within your component add method:

@Component({ })
class XYZ {
    // ... some code

    public onSelect(broker) {
        // Do what you need with broker?
    }
}
