Send value from view to method and vice versa

Hi,
If you want to send a value to your controller, you are many ways switch your problem. Here, we don't know if you want t send a vlue when you click on a button (picture, etc.) or when a time is elapsed, etc..
A controller is to manage your wiew and call models.
If you don't need to do that and simply modify a value without using models, a simply helper or library is sufficient.
