Call generic method with type from javascript using ajax

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",
        },
    ...
