仅在选择单选按钮时添加数字

Question

I want to add a number to total amount based on radio button select only if user selects radio button with value = "serfeeadd" so I need to check it, get it and add it to the total but I can't figure out why its not working but when I remove scope = this and only use $scope directly it kinda works, I just need the value assigned to the variable.

I am trying to build a magento wristband designer app everything is built only stuck with this part .

The code has been modified to provide you guys with an overview for anything more you can let me know.

 var app = angular.module('wdWristbandDesigner', []); app.controller("fontCtrl", MainController); function MainController($scope){ //scope var scope = this; scope.foo = function(){ if (scope.serialisationFeeCheck == 'serfeeadd') { scope.serialisationFee = 10; console.log(scope.serialisationFeeCheck); } else { scope.serialisationFee = 0; }; } }; 

 <section class="wd-section" ng-controller="fontCtrl as fs"> <input type="radio" name="serialno" data-ng-model="serialisationFeeCheck" value="no" >No <br> <input type="radio" name="serialno" data-ng-model="serialisationFeeCheck" value="our">Yes(Our Choice) <br> <input type="radio" id="chk" name="serialno" data-ng-model="serialisationFeeCheck" value="serfeeadd" >Yes(Your Choice) <button typ="button" ng-click="foo()" >click</button> </section>

ng-click应该是fs.foo（），所有ng-models都需要将fs对象应用于它们。
