I tried your code in ver 4.2 Beta but got the following error can you help in this regard.
The model item passed into the ViewDataDictionary is of type 'System.Collections.Generic.List`1[Nop.Web.Models.Catalog.ManufacturerBriefInfoModel]', but this ViewDataDictionary instance requires a model item of type 'System.Collections.Generic.IList`1[Nop.Web.Models.Catalog.ManufacturerModel]'.
Thanks in advance
As per error, You returning model - Nop.Web.Models.Catalog.ManufacturerBriefInfoModel from Action Method and using model Nop.Web.Models.Catalog.ManufacturerModel in view page.
Both models should be the same.
