I want to add my selectedDocuments object ‘comment’ item with it’s value (so that i want to show this input in a form where this selectedDocuments object values are rendered and after submmiting this input i want it to be added to selectedDocuments object ) i have tried several varaints here is my code:
var variableManager = camForm.variableManager;
$scope.refusalComment=null;

    camForm.on('form-loaded', function() {
      // tell the form SDK to fetch the variable named 'document'
    variableManager.fetchVariable('selectedDocuments');
    });
    camForm.on('variables-fetched', function() {
      // work with the variable (bind it to the current AngularJS $scope)
       $scope.refusalComment = variableManager.variable('refusalComment').value;
      console.log( $scope.refusalComment+"=========refusalComment==========");
      $scope.selectedDocuments =ConvertToJsonArray(variableManager.variable('selectedDocuments').value);    
    });
function ConvertToJsonArray(arr){
//I  have  replaced FinalResult with data
var  jsonArray=[];
var json=$scope.json={};
var json1=$scope.json1={};
var json2=$scope.json2={};
json=JSON.parse(arr);
json1=json.FinalResult;
json2=JSON.parse(json1);
//console.log(json1);
return json2;
}
function EnrichValue(data,comment){
var json=$scope.json={};
var json1=$scope.json1={};
json=JSON.parse(data);
json1=json.FinalResult;
json1=JSON.parse(json1);
for(var  i=0;i<Object.keys(json1).length;i++){
json1[i].comment=comment;
}
console.log(json1);
return json1;
}
