func IndexController(w http.ResponseWriter , r *http.Request){

if r.Method == "POST"{

    data := &Index{
        Title: "Hello",
        Body:  "Welcome to the WebGo.",
    }

    ff := renders.Sample{Temppath:"templates/index.tmpl",Data:data}

Declare field Data in struct Sample as interface{}:

type Sample struct {
    Temppath string
    Data     interface{}
}

The type Sample then can also be used in other controllers as placeholder of any data which is going to be passed to template.
