trying to set the same task but with different data each one in kivy

Question

how i can run the same task with different data? i tried everything but is always the same. for example i put "yes" in one textinput and "no" in another and start printing it in one thread, but if i try to erase the data of the input for start a new one with other data it will also erase it from the thread that is already running, for example again "yes" and "no" if i delete "yes" the thread will also delete it and continue printing only "no". how can i resolve this? Code is down below
