Debugging on Mobile.

[mwalter]

What is the most common way to debug javascript on a remote device (Zebra Tablet)?

I have an application in which the Javascript will enable/disable a button on the form based on the result of an Ajax call. The program will populate some fields and then set the "disabled" property to "false". I see the fields being populated but the buttons are not being enabled. This only happens on a few of over 50 devices. But it's the same devices. I've tried clearing the cache and put cache buster code in the javascript load.
