Android - Binding adapter not working

Question

I have create a binding adapter to display picture with picasso, but it doesn't work. I have the following error :

Found data binding errors. ****/ data binding error ****msg:Cannot find the setter for attribute 'app:loadPicture' with parameter type java.lang.String on android.widget.ImageView. file:/home/groupevsc.com/mathieu_labar/Documents/Projects/android-jetpack/app/src/main/res/layout/activity_detail_movie.xml loc:27:31 - 27:52 ****\ data binding error ****

Here is my binding adapter :

object CommonBindingUtil {

    @JvmStatic
    @BindingAdapter("loadPicture")
    fun loadPicture(view: ImageView, text: String) {
        Picasso.with(view.context)
                .load(text)
                .error(R.drawable.ic_movie_24)
                .fit()
                .placeholder(R.drawable.ic_movie_24)
                .into(view)
    }

}

And my XML has attribute "app:loadPicture" :

<ImageView
    android:id="@+id/picture"
    android:layout_width="@dimen/material_image_simple_width"
    android:layout_height="wrap_content"
    android:adjustViewBounds="true"
    android:scaleType="fitXY"
    android:src="@drawable/ic_movie_24"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:loadPicture="@{viewModel.movie.Poster}"/>

Here is my code

@JvmStatic
    @BindingAdapter({"bind:loadPicture"})
    fun loadPicture(view: ImageView, loadPicture: String) {
        Picasso.with(view.context)
                .load(loadPicture)
                .error(R.drawable.ic_movie_24)
                .fit()
                .placeholder(R.drawable.ic_movie_24)
