How to find if pointerMove was stopped?

Hi there,

I have an ionic range component in my page and I call a method on pointerMove event. I stop that method on pointerUp. But the problem is that if a user move the range slider and then stop moving the slider but doesn’t take his finger up the stop method never call and my app is not correctly working.
I want to know if there is a way to find out when user stop moving his finger.

Any help will be appreciated.
