Custom infopath task doesn't update in visual studion sequential workflow

Question

Hi all,
I have a probleme with an InfoPath task form
I've been looking for a solution to my problem for few days now with now success.
I developped a visual studio  sequential workflow, i than designed an infopath Edit Task Form
my form have following fields :
Title : tbTitle
Status : tbStatus
Assigned To : tbAssignedTo
Start Date : pStartDate
Due Date : pDueDate
Button  to submit data to host
Button to cancel
I also have these data connctions
Data connection to send Data to host
Data Connection to retreive data using xml schema
My workflow looks like this :
onWorkflowActivated -> replicator
in my replicator i have an activity that do the follwing :
createTask -> onTaskCreated -> While not completed -> onTaskChanged -> completeTask
My workflow just work fine.
i added the new custom info path form to my workflow and work fine too, the only probleme i have is that my task don't load modified data after the task is comleted, in other words : i use the form to complete task -> task is recognaised as complete and
workflow too but when i re-open the task it shows in progress.
The form don't show modified data.
I really need your help, i spent a lot of time googling and testing sevral solutions but no success, my form dosn't seem to store data in tasklist.
Thanky in advance.
some sample of my code are here :
private void readTask_MethodInvoking(object sender, EventArgs e)
readTask.TaskId = Guid.NewGuid();
this.readTask_TaskProps.TaskType = 1;
readTask_TaskProps.Title = TaskTitle;
readTask_TaskProps.StartDate = DateTime.Now;
readTask_TaskProps.DueDate = DateTime.Now.AddDays(7);
readTask_TaskProps.ExtendedProperties["title"] = TaskTitle;
readTask_TaskProps.ExtendedProperties["status"] = CurrentTaskStatus;
readTask_TaskProps.ExtendedProperties["assignedTo"] = TaskAssignedTo;
readTask_TaskProps.ExtendedProperties["startDate"] = String.Format("{0:d}", readTask_TaskProps.StartDate);
readTask_TaskProps.ExtendedProperties["dueDate"] = String.Format("{0:d}", readTask_TaskProps.DueDate);
readTask_TaskProps.AssignedTo = TaskAssignedTo;
readTask_TaskProps.SendEmailNotification = false;
isTaskFinished = false;
private void onReadTaskChanged_Invoked(object sender, ExternalDataEventArgs e)
isTaskFinished = onReadTaskChanged_AfterProps.ExtendedProperties["tbStatus"].Equals("Completed");
