How do I specify error member key in ASP.NET MVC CustomValidation?

Question

I'm trying to add CustomValidation and make it return error for

Html.ValidationMessageFor(m => m.SubleaseCompany)

[CustomValidation(typeof(CreateSpaceModelValidation), "ValidateCreateSpaceModel")]
public class CreateSpaceModel
{
    public Building Building { get; set; }
    public Space Space { get; set; }

    public string SubleaseCompany { get; set; }
}

public class CreateSpaceModelValidation
{
    public static ValidationResult ValidateCreateSpaceModel(CreateSpaceModel model)
    {
        return new ValidationResult("You should specify Sublease Contact", new[] { "SubleaseCompany" }).;
    }
}

I'm using second argument for ValidationResult constructor (memberNames) but this doesn't seem to work.
