bootstrap slider not showing tooltip on iphone 6, mobile device

Hi just found an issue on bootstrap sliders which you can download from http://ift.tt/1lwYnrc or http://ift.tt/1bHa8Vr

both of these plugins seem to be having the same issue on iphone 6 - the tooltip is not showing up when sliding the slider. I have checked only on iphone 6 but i assume the same issue is for other mobile devices. Has anyone found a solution for that?
