jquery mobile 1.3.1 data-inline="True" not working

jquery mobile 1.3.1 data-inline="True" not working

I've upgraded my application from jquery.mobile 1.1.0 to 1.3.1 and run across a problem.
(I'm using asp.mvc 3)

I've got buttons I create using the ActionLink() extension method that accepts html attributes as IDictionary<string, object>.
One of the attributes I specify is "data-inline"=true and in the resulting html page it renders as data-inline="True"
With jquery.mobile 1.1.0 this works, but with 1.3.1 it does not (the data-inline is ignored).

I've worked around this by specifying the value of the "data-inline" value as string in the dictionary, but this looks like a bug to me, I'm just not sure if the bug is in jquery.mobile or asp.mvc :)

Thanks,
Nadav
