I want to create a funcMap from all methods of a particular struct.

I have the following code:

type templateFuncs struct{}

func (t templateFuncs) UnescapeHTML(html string) template.HTML {
    html = strings.ReplaceAll(html, " ", "")
    html = strings.ReplaceAll(html, "nn", "n")
    return template.HTML(html)
}

func (h *Handler) templateFuncs() template.FuncMap {
    funcMap := make(template.FuncMap)
    tplFuncs := &templateFuncs{}

    rType := reflect.TypeOf(tplFuncs)

    for i := 0; i < rType.NumMethod(); i++ {
        method := rType.Method(i)
        funcMap[method.Name] = method.Func.Interface()
        fmt.Printf("method %#v", method)
    }

    return funcMap
}

However, this assigns a function where the first argument is a pointer receiver.

"UnescapeHTML":(func(*http.templateFuncs, string) template.HTML)(0x10333eb40)

Is there a way to assign the original function with just the string argument to the funcMap? Is there a better way for approaching this problem?
