Hello Kevin,
Thanks for your consern an help, i have made a mistake, but i have read some documentation and I found my fault, but all because your example. So the textField only update if the user press a button or made a command to call another function who as responsible to update the fields. So initialy in the function where I pass the parameter's I dont declare the parameter "app", this way the function dont found the scope and this way dont appear anything in text field desired.
Thanks again, cheers
