Total Sum by Angular JS

In the index.cshtml file: 

 <tr>
                        <td></td>
                        <td ><b>Total:</b> </td>
                        <td><p id="gridTotalamount">{{GetSummOfAmount(PConsultData)}}</p></td>
                        <td></td>
 </tr>

In the Js File(PatientConsult.js):

 $scope.GetSummOfAmount = function (PConsultData) {
        var summ = 0;
     
        for (var i in PConsultData) {
            summ = summ + Number(PConsultData[i].Amount);
        } 
   


        return summ;

    };



See how palindrome works.
