Click Listeners for onStartIconClickListeners not working in TextInputLayout

I am implementing onstartIconClickletener using a custom attribute and Binder method

My Layout element is

<com.google.android.material.textfield.TextInputLayout
                android:id="@+id/text.layout.email.and.phone"
                style="@style/Widget.MaterialComponents.TextInputLayout.FilledBox"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_margin="@dimen/_16sdp"
                android:hint="@string/txt_email_phone"
                android:textColorHint="@color/bg_input_text"
                app:boxStrokeColor="@color/bg_input_text"
                app:hintTextColor="@color/bg_input_text"
                app:layout_constraintLeft_toLeftOf="parent"
                app:layout_constraintRight_toRightOf="parent"
                app:layout_constraintTop_toBottomOf="@id/toolbar"
                app:prefixTextColor="@color/text_color_white_1"
                app:startIconDrawable="@drawable/ic_down_arrow"
                app:startIconTint="@color/colorPrimaryDark"
                app:onStartIconClicked = "@{(view)->viewModel.onStartIconClicked(view)}"
                app:prefixText="@{viewModel.prefixText}">

I created an interface with one single method

public interface StartInconOnClickListener {
    void onStartIconClicked(View view);
}

In my BindingAdapter

@BindingAdapter({"app:onStartIconClicked"}) 
public static void setonStartIconClickedListener(TextInputLayout textInputLayout, StartInconOnClickListener newListener) { 
    View.OnClickListener onClickListener = new View.OnClickListener() { 
        @Override public void onClick(View v) { 
            newListener.onStartIconClicked(v); 
        } 
    }; 
    textInputLayout.setStartIconOnClickListener(onClickListener); 
} 

But clicking the startIcon it is invoking onClick in the BindingAdapter, but it is not calling my lambda function in the ViewModel

My Lamda function in the view model is

public void onStartIconClicked(View view) {
        prefixText.set("+91");
        Event event = new Event(Boolean.valueOf(true));
        _showCountryCodeDialog.setValue(event);
    }

I spent the whole day. now I am looking for help
