在ionic 2列表项中实现动态警报弹出窗口，并在项中设置所选值

Question

在ionic 2应用程序中，我有一个包含动态项目的列表。在每个项目中，我都有按钮项目。单击特定按钮项时，将弹出动态警报弹出窗口。一旦我从弹出窗口中选择一个选项，该值将被设置为项目内容。但就我而言，当我从弹出窗口中选择一个值时，它会出现在所有项目中。我想将其设置为唯一选择或单击的项目。请帮我解决这个问题。

HTML代码

    <ion-item *ngIf="isGroupShown(i)">

        <ion-card-content class="no-left-right-padding card_class">
        <ion-row>
            <ion-col col-6>
                <ion-icon name="card" end (click)="removeItemFromCart(item)"></ion-icon>
                <span margin-left class="service-item">{{item.cost}} BD</span>
            </ion-col>
            <ion-col col-6>
                <ion-icon name="clock" end (click)="removeItemFromCart(item)"></ion-icon>
                <span margin-left class="service-price">{{item.time | number: '1.0-0'}} Mins</span>
            </ion-col>
        </ion-row>
        </ion-card-content>

    <ion-item button class="employee_item" margin-left no-lines (click)="select_emplyee(i)"> {{employee_data||'Select Employee'}}</ion-item>

    </ion-item>
