Enter a number in the field do not use the keyboard

I need to make it so that when the buttons "-" and "+" are pressed, the number in the field changes. So that you do not use the keyboard to enter a number in the field

 

Does anyone have a solution? please share

Regards

    The formula in the buttons would be:

     

    Number := Number + 1

     

    and

     

    Number := Number - 1
