ImageLoad with custom controller

my project is similar to this #6 and the customController i made with this is not working at all , dont know why

open class CustomController {

    fun loadUri(view: ImageView, uri: Uri) {
        Picasso.with(view.context).load(uri).placeholder(R.drawable.default_image).into(view)
    }

}
