Ion-range change value when swipe the screen

Hello, I would like to change the value of the ion-range when user moves the knob only and not when the user swipes the screen and accidentally touch the range slider. So, this is awkward for UX.

I used touchmove or touchend and also some gestures like pan to avoid this problem, but these doesn’t work. Can anyone explain the best way to avoid this problem?

Thank you.
