Can i add three buttons in option button

   <ion-option-button class="button-balanced">
                      <span class="ion-plus" ng-click="addCount(item)"></span>
                      <span class="ion-android-cart" ng-click="addItemCart(item)"><span class="cart-cnt">{{item.count}}</span></span>
                      <span class="ion-minus" ng-click="minusCount(item)"></span>
                  </ion-option-button>

This not triggering any click functions. Anybody tried this?
