如何使用ui-grid更新列值

Question

I am using ui-grid table plugin.i want to update count value if user enter same id. if id is not same i want to update whatever user enter in the count textbox value. count will increase only if user enter same id. push function only should work if user enter new id otherwise only count increase. how can i do it?. I need anyone help.

var app = angular.module('app', ['ngTouch', 'ui.grid']);
app.controller('MainCtrl', ['$scope',
function($scope) {
    $scope.gridOptions = {};
    $scope.Delete = function(row) {
        var index = $scope.gridOptions.data.indexOf(row.entity);
        $scope.gridOptions.data.splice(index, 1);
    };
    $scope.gridOptions.columnDefs =[{ field:"Id", displayName: "Id"},{ field:"Display", displayName: "Display"},{ field:"Count", displayName: "Count"}];

       $scope.addedid=0;     
       $scope.myVaridarr=[];
      $scope.addid = function(myVarid,countVar){

    $scope.addedid =  +$scope.addedid+ +countVar;

          var addToArray=true;
    for(var i=0;i<$scope.myVaridarr.length;i++){
    if($scope.myVaridarr[i]===myVarid){
    addToArray=false;

    alert("Id already is there"); 
     $scope.gridTwoValue =
      {
                "Id": myVarid,
        "Display": "Carney",
        "Count":  $scope.addedid 
      };
     $scope.gridOptions.data.push ( $scope.gridTwoValue ); 
    }
    }
    if(addToArray){alert("New Id");
    $scope.myVaridarr.push(myVarid); 
    $scope.gridTwoValue =
      {
                "Id": myVarid,
        "Display": "Carney",
        "Count":  $scope.addedid 
      };
    $scope.gridOptions.data.push ( $scope.gridTwoValue ); 
    }};  }]);

                $scope.gridOptions.data[index] = {
                    "Id": myVarid,
                    "Display": "Carney",
                    "Count": $scope.addedid

                };
