I was adding a on-hold event to a link in that case “disable-user-behavior” appears when on-hold event is fire 1st time.
use ng-disabled=‘disabled’ directive
<a class="addBTN" ng-click="increaseIntensity()" on-hold="increaseIntensity()">Increase</a>
Why i have to ng-disabled=‘disabled’ directive?
instead of anchor like use button your issue will reslove
