Server JObject as parameter in breeze saveChanges, has null value when used with internet explorer

Server JObject as parameter in breeze saveChanges, has null value when
used with internet explorer

I am using breezejs version 1.4.0 and metadata version of 1.0.5 with
durandaljs to build SPA. I have a method called saveChanges that returns
SaveResult object. The method is configured as stated in breeze
documentation. Here is the method that is used by breeze to save entity
changes.
[HttpPost] public SaveResult saveChanges(JObject moduleItems) { return
_repository.SaveChanges(moduleItems); }
When this is used with other browsers i.e chrome, Safari, firefox etc,
everything works fine. But when I use internet explorer to run the
application, my moduleItems as JObject always has null value. I trying to
imagine how IE deals with JSON object; Please, any help will be
appreciated. Thanks in advance.
