WebApi with Odata NextPage and Count not included in JSON response

I have a webapi method that I want to swap oData, etc. I followed the example at http://www.asp.net/web-api/overview/odata-support-in-aspnet-web-api/supporting-odata-query-options

My method looks like this:

public PageResult<UserViewModel> GetUsers(ODataQueryOptions<UserViewModel> options)
{
    var settings = new ODataQuerySettings()
    {
        PageSize = 2
    };

    var results = UserLogic.GetUsers(userId, UserManager, _db);
    var filtered = options.ApplyTo(results, settings);

    var pagedResult = new PageResult<UserViewModel>(
        filtered as IEnumerable<UserViewModel>,
        Request.GetNextPageLink(),
        Request.GetInlineCount());
    return pagedResult;
}  

      

        
        
        
      

    

That counting counting is the link of the next page and the correct OData parameters are applied, i.e. sort order, etc. When I return it in my api method, the data is correct, but the score and the following link are not used, t appears in my json.

Am I missing a setting to enable this?

i.e. this is my json response:
