You should try using the DisplayName attribute

    [DisplayName("Seconds")]
    public double Duration { get; set; }

Figured out the problem. Am using Unity as an IOC and to reduce unity resolve errors I added this in the UnityConfig:

container.RegisterType<ModelMetadataProvider, EmptyModelMetadataProvider>();

which wiped out the data attributes. changed it to this and it worked fine:

container.RegisterInstance<ModelMetadataProvider>(ModelMetadataProviders.Current);
