Plus/minus buttons cause scrolling twice

[GoogleCodeExporter]

(some copied from identical isssue 
http://code.google.com/p/mobiscroll/issues/detail?id=68&can=1&q=twice )

What steps will reproduce the problem?
1. Create a date scroller with plus and minus buttons.
2. Press the buttons.
3. Reels scroll two times instead of one

What is the expected output? What do you see instead?
The Number should always increment/decrement by one. But often they 
increment/decrement twice.

What version of the product are you using? On what operating system?
Latest Mobiscroll 2.2, on Android 4.0, 4.2 and other 4.x devices

Please provide any additional information below.
Problem existed in 2.0.1, updated to 2.2 and problem persisted. Happens on 
every click of the buttons on Nexus 7 tablet running Android 4.2

This works as intended. If you hold your finger on the +/- buttons, the wheels 
are scrolled until touchend.
The default interval is 300ms (meaning that if the tap is longer than that, it 
will scroll 2 or more values), but you can change it through the 'delay' option 
if you don't like it:

$('#test').scroller({
  preset: 'date',
  delay: 1000,
});

Thanks for your reply. I beg to differ that it works as intended. In the case 
of the tablet, every single tap results in a scroll of at least two units, 
instead of one. So no matter the length of the tap, the scroller moves twice. I 
will be changing it in my version but it is definitely an issue on an Android 
Nexus 7 table inside of a Android WebView.

I confirm the bug, on Nexus 7 running Android 4.2. 

Set delay to a longer time doesn't resolve the problem, still scrolls twice on 
a single tap.

I'm using also jQuery Mobile 1.2.0 final and Cordova 2.1.0.

Just experienced this bug with MobiScroll 2.6.2 on three different Android 
tablets running 4.2.2. 
Tested with default browser as well as UC browser - both had the same behavior. 

Was this fixed in 2.4.2 and then broken again in later versions?
