sitecore - Glass mapper does not load item childeren -

we facing issue in glass mapper 4.0 not load item children.

here our controller class , inheriting glasscontroller:

public class carouselcontroller : glasscontroller {     public actionresult getcarousel()     {         model = this.getdatasourceitem<carouselviewmodel>();         return view(model);     } } 

and here our view model:

public class carouselviewmodel:carousel_folder {           [sitecorechildren]     public virtual ienumerable<carousel> carousels { get; set; } } 

we parent node information not childeren (carousels) in result

here result get:

[result image][1]

also, following classes generated tds:

[sitecoretype(templateid = icarousel_folderconstants.templateidstring )] //, cachable = true public partial interface icarousel_folder : iglassbase {} 

carousel template inheriting 2 templates content base , image base.

i had issue before, me added [sitecorechildren(islazy = false)] model , works fine, in case should :

public class carouselviewmodel:carousel_folder {      [sitecorechildren(islazy = false)]     public virtual ienumerable<carousel> carousels { get; set; }       }
