Hi,

As you call Umbraco.Content(id) you are actually getting the published content back with all the cultures in it.

when you call model.Value("someProperty") that will be returning the default (so Swedish in your case) but you can call it with the culture name to get the other language versions.

e.g

var myValue = model.value("someProperty", cultureName) 

from an ajax call the controller won't know what language you want so you will need to pass that as part of your method name so a method like this should work* :

[HttpGet]
public string GetSomething(int id, string culture)
{
    var content = Umbraco.Content(id);
    return content.Value<string>("someValue", culture);
}

*with null checks and all the other stuff
