2 ng-clicks在ng-repeat Ionic AngularJs中调用相同的功能

Question

enter image description here

我们在ng-repeat中有加号和减号按钮。每个按钮应在特定文本框内增加或减少值。无论点击按钮只有一个事件正在触发，有2个递增和递减功能。虽然两个按钮都有不同的功能名称。

这是我用来触发事件的控制器代码

    app.controller('MultiCheckOutCtrl',function($ionicPlatform,$ionicHistory,$rootScope,$scope,$state,$http,webservices,myconfig,$ionicPopup,$ionicLoading){
console.clear();
 $rootScope.$ionicGoBack = function(backCount) {
$ionicHistory.goBack(backCount);
//alert("back button");
$( ".datepicker" ).datepicker("hide");
};
$ionicPlatform.registerBackButtonAction(function() {
$( ".datepicker" ).datepicker("hide");
$ionicHistory.goBack();
}, 100);
    // increment for + button //
   $ionicLoading.show({
      template: "Please Wait."
   });
    $scope.decrement = function(){
      alert("decrement");
    }//end of decrement
    $scope.increment = function(){
      alert("increment");          
    }
  $scope.userBookingDetails = {};
  $scope.usrdata={};
  $scope.errorStatus=false;         webservices.getPackagesBasedOnResortId($scope.resortid).success(function(data) {
        //console.log("Inside MultiCheckOutCtrl controller : "+data[0].bannerimage); 
        $scope.userBookingDetails = data;
        //console.clear();
        //console.log(data);
        $ionicLoading.hide();
    });      
});

这是我的观点文件：

`<div class="card" ng-repeat="r in userBookingDetails">
  <div class="list" >
    <div class="item item-divider">
      {{r.packagename}}
    </div>
    <label class="item item-input">
      <div class="input-label col col-30">
        Adults (Per Ticket) <span>Rs. {{r.adultprice}} </span>
      </div>
      <div class="input-label col col-20">
        <button class="button  button-calm mybtn" ng-click="decrement()">
            -
        </button>
      </div>
      <div class="input-label col col-30">
        <input type="text" class="qty" /> 
      </div>
      <div class="input-label col col-20">
         <button class="button  button-calm mybtn" ng-click="increment()">
            +
        </button>
      </div>
    </label>
    <label class="item item-input" ng-if="r.childprice!=0">
      <div class="input-label col col-80">
        Children (Per Ticket) <span>Rs. {{r.childprice}}  </span>
      </div>
      <input type="number" name=""  ng-model="userBookingDetails[$index].mobilechildqty" placeholder="0" value="0" class="col col-20" side="right" style="float:right;" >
    </label>
  </div>
</div>`
