I'm trying to select a product from the suggest box. When a select a 
product, the qty and unit cost as to appear in the text box automatically 
which is done using angularjs ng-model. The Add Item in the image will add 
an empty row, where we can select product/service for invoice. 

Now the issue is, when i click Add Item twice and select product/service in 
the first row, qty and unit cost is updated for the 2nd row. Can anyone 
help me out in this issue Thanks in advance.



Here is my html:


      <div class="row" ng:repeat="item in invoice.items">
        <div class="col col-50">
          <ion-autocomplete name="product" ng-model="item.productId" 
item-value-key="productId"
            item-view-value-key="productName" items-method=
"getProducts(query)"
            items-method-value-key="items" items-clicked-method=
"productClickCallBack(callback)" 
            ng-value="calculateAll()" placeholder="Product Or Service" 
required/>
        </div>
        <div class="col">
          <input type="number" maxlength="4" placeholder="Qty"
            ng-model="item.qty" ng-change="calculateAll()">
        </div>
        <div class="col">
          <input type="number" maxlength="6" placeholder="Unit Cost"
            ng-model="item.unitCost" ng-change="calculateAll()">
        </div>
      </div>

  </div>



Here is productClickCallBack(callback) method definition:


   $scope.productClickCallBack = function(callback) {
      $scope.item.qty = 1;
      $scope.item.unitCost = callback.item.sellingPrice;
    };
