Using buttons to increase/decrease the value

Hi,

What is the most straightforward way to add -/+ buttons around or next to the number field?

I already added the buttons, wrote the OnClick functions that increase and decrease the value by one when clicked. However, with this solution the calculation isn’t working properly. I guess my solution isn’t the correct one. Do you have some ready solution for this kind of need?

And thank you for the awesome plugin!
