Scrolling works, but clicking does not

[farfalletonde]

I tried implementing this view. Although scrollable attribute works, clicking does not seem to work on my project. (I am using the latest version) This is my code:

    <com.willy.ratingbar.ScaleRatingBar
            android:id="@+id/rating"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:srb_drawableEmpty="@drawable/ic_star_empty"
            app:srb_drawableFilled="@drawable/ic_star_full"
            app:srb_clickable="true"
            app:srb_scrollable="true"
            app:srb_isIndicator="false"
            app:srb_numStars="5" />
