<a  md-icon-button [routerLink]="['./new']" queryParamsHandling="merge"
                mdTooltip="Add Document" [disabled]="isAddButtonDisabled(selectedAssociation)">
                <md-icon>add</md-icon>
            </a>
The button is firing click event even when the button is disabled. Is there a way to prevent the click?
