kendo ui - What is column syntax for odata linked table -

I have a general WCF service, where there is a department that relates to a department.

Name

Using the razors I can find the foreign key column that I want, but I did not get the syntax for javascript. I'll consider something like this:

  column: [{field: "department # name", filterable: wrong},  

but I can not Find the right syntax anywhere.

get answers, just expand data source

  type "Odata", transport: {read: {url: "http: // localhost: 49168 / RapDataService.svc / product", data: {$ extension: "department"}}},  

And then the syntax I was seeing was dot.

  {region: "Department.Name", title: "Afflecking", filterable: true},
