SSIS Script Component - How to modify the Output0Buffer

I've a script component which accepts records from SQL Azure database table. The script then invokes a web service, which returns the number of failed and success records.

For all the records, I would like to add the Status field which has either "success" or "fail" and this gets output from script component.

I then log those output into a text file.

Problem:
I'm not been able to add status for each input records since the web service call only happens on post execute.

I tried this but still doesn't work:

public override void Input0_ProcessInputRow(Input0Buffer Row)
{
         listOfData.Add(new ClockData 
         {
             TimeClockID=Row.TimeClockID,
             PersonID=Row.EmployeeCode,
             LocationCode=Row.ClockInServiceContextID,
             ClockInDateTime=Row.ClockInDateTime,
             ClockOutDateTime=Row.ClockOutDateTime

         });
 }

 public override void CreateNewOutputRows()
 {
     MessageBox.Show("Test CreateNewOutputRows");
     MessageBox.Show(listOfData.Count.ToString());
     foreach (var item in listOfData)
     {
         Output0Buffer.AddRow();
         Output0Buffer.EmployeeCode = item.PersonID;
         MessageBox.Show(item.PersonID);
     }
 }

Everything in a Transformation is done within Input0_ProcessInputRow
The solution would essentially be

public override void Input0_ProcessInputRow(Input0Buffer Row)
{
         listOfData.Add(new ClockData 
         {
             TimeClockID=Row.TimeClockID,
             PersonID=Row.EmployeeCode,
             LocationCode=Row.ClockInServiceContextID,
             ClockInDateTime=Row.ClockInDateTime,
             ClockOutDateTime=Row.ClockOutDateTime
         });
         Output0Buffer.AddRow();
         Output0Buffer.EmployeeCode = item.PersonID;
         MessageBox.Show(item.PersonID);
}

You may be able to perform the output steps in PostExecute, CreateNewOutputRows is not run in Transformation, only in Destination scripts.
