Hi I have problem in making web view. is Like if user hit payment button is should be open in browser by default . but I m not getting how to integrate payment gateway in web view.

Here is my payment.html

<ion-content padding="'true'" class="has-header">
    <form class="list">
        <ion-radio>Credit Card</ion-radio>
        <ion-radio>Net banking</ion-radio>
        <ion-radio>COD</ion-radio>
    </form>
<!--  <button class="button button-calm button-block ">PAY</button> -->
	<button id="btnSubmit" ng-click="paymentOpen()">Make a Payment</button>

</ion-content>

and here is my controller for payment

.controller(‘paymentCtrl’, function ($scope, $ionicPopup, $state,$location,$ionicHistory,$cordovaInAppBrowser) {

function handleResponse(res) {
            if (typeof res != 'undefined' && typeof res.paymentMethod != 'undefined' && typeof res.paymentMethod.paymentTransaction != 'undefined' && typeof res.paymentMethod.paymentTransaction.statusCode != 'undefined' && res.paymentMethod.paymentTransaction.statusCode == '0300') {
                // success code
            } else {
                // error code
            }
        };

 $scope.paymentOpen = function () {


	//e.preventDefault();

            var configJson = {
                'tarCall': false,
                'features': {
                    'showPGResponseMsg': true
                },
                'consumerData': {
                    'deviceId': 'WEBSH2',	//possible values 'WEBSH1', 'WEBSH2' and 'WEBMD5'
                    'token': 'xxxxxxxxxxxxxxxxxxxx45678gfrhh',
                    'returnUrl': 'https://www.tekprocess.co.cxcxcxccccxxx',
                     'responseHandler': handleResponse,
                    'paymentMode': 'all',
                    'merchantId': 'T14',
                    'consumerId': 'c96',
                    'consumerMobileNo': '9876543210',
                    'consumerEmailId': 'test@test.com',
                    'txnId': '1481197581115',   //Unique merchant transaction ID
                    'items': [{
                        'itemId': 'test',
                        'amount': '10',
                        'comAmt': '0'
                    }]
                }
            };

            new Card(configJson).init();

 }
// $scope.paymentOpen2 = window.open($scope.paymentOpen, {openExternal: true});

})

please help me out how to integrate this json config in web view.
