Can't seem to find any example on how to call generic method with type from javascript using ajax

    public virtual JsonResult GetData<T>(SomeClass firstParam) where T : class, ISomeInterface
    {
       ...
    }

Call with ajax

    ...
    ajax:
        {
            url: "@Url.Action("GetData", "Controller")",
            type: "POST",
        },
    ...

Edit 1: Just to clarify duplicate report. I'm trying to call generic method not controller so something like this

 ...
    ajax:
        {
            url: "@Url.Action<SomeClass>("GetData", "Controller")",
            type: "POST",
        },
    ...
