Hi all, 

Im using Umbraco 7.1.6 and have set up a controller + model and am successfully rendering views / partialviews, but i have stumbled across a problem now, that ive spent a while trying to get past with no luck.

My error occurs on (public RaknaTeckna() : this(new UmbracoHelper(UmbracoContext.Current).TypedContent(UmbracoContext.Current.PageId)) { }) UmbracoContext is null.

public class RaknaTeckna : RenderModel
{
        public string somethings { get; set; }

        public RaknaTeckna() : this(new UmbracoHelper(UmbracoContext.Current).TypedContent(UmbracoContext.Current.PageId)) { }
        public RaknaTeckna(IPublishedContent content, CultureInfo culture) : base(content, culture) { }
        public RaknaTeckna(IPublishedContent content) : base(content) { }
}

Im calling my controller from an ajax call (see below, have changed out the data im sending in). I get into my controller just fine and the objects i send in with the data also arrives, but because im calling the controller directly the UmbracoContext is null. 
$.ajax({

            cache: false,
            type: "POST",
            url: '/umbraco/surface/mycontroller/myaction/',

            data: { "somethings": somethings },

            success: function (data)
            {
                $("#boxes").html('');
                $("boxes").html(data);
            },

            error: function (xhr, ajaxOptions, thrownError)
            {
                console.log(xhr);
                $("#calculateerror").html(xhr);
             }
         });    

How can i fill the UmbracoContext if coming to the controller from ajax?
