Golang set struct field using reflect

I am currently doing the following

func Test(controller interface{}) {
    controllerType := reflect.TypeOf(controller)
    controllerFunc := reflect.ValueOf(controller)
    controllerStruct := reflect.New(controllerType.In(0))
    for i := 0; i < controllerStruct.Elem().NumField(); i++ {
        if controllerStruct.Elem().Field(i).Kind().String() == "ptr" {
            controllerStruct.Elem().Field(i).Set(
                reflect.New(
                    controllerStruct.Elem().Field(i).Type(),
                ).Elem(),
            )
        }
    }
    controllerFunc.Call([]reflect.Value{
        controllerStruct.Elem(),
    })
}

Using the following function call

Test(controllers.Test.IsWorking)

type Test struct {
    Name string
    H    *Hello
}

type Hello struct {
    Friend string
}

func (t Test) IsWorking() {
    log.Println(t.H)
}

t.H is always nil even tho I am setting it on the for loop. Also I am not sure if this is the correct way to make this since what about if Hello struct contains another pointer to a struct. Is there a better method to achieve what I am trying to do and why is t.H nil if I am setting it up
