Textbox contains English version of month-name regardless language configuration

[Xozin]

my config:
{
autoClose: true,
singleDate : true,
showShortcuts: false,
language:'ru',
format: 'D MMMM'
}

but in textbox i see: "21 January" instead of "21 Января"

I believe this is because those dates are passed back from moment and it's locale isn't set to Russian. I am having the same issue. Maybe look at #282 for a fix.
Also I think you should use moment with locales for it to work.
