post_row_actions not working for hierarchical post type

I'm working on a plugin where I have a Custom Post Type (CPT) registered and I need to add custom row actions to that particular post type. But could not make the following code hooked to post_row_actions work:

function ttest_copy_button( $actions, $post )
{
    // var_dump($actions);
    if( 'ttest' === $post-post_type ) {
        // pass nonce to check and verify false request
        $nonce = wp_create_nonce( 'copy_content' );

        // add our button
        $actions['copy_content'] = 'a data-nonce="'. $nonce .'" href="javascript:" role="button"'. esc_html__( 'Copy Content', 'ttest' ) .'/a';
    }

    return $actions;
}

add_filter( 'post_row_actions', 'ttest_copy_button', 10, 2 );

My CPT code is:

function ttest_register_cpt() {
    register_post_type( 'ttest', array(
        'labels'              = array(
            'menu_name' = __('TTest', 'ttest')
        ),
        'hierarchical'        = true,
        'description'         = __( 'Get the test information', 'ttest' ),
        'supports'            = array( 'title', 'editor', 'excerpt', 'page-attributes' ),
        'taxonomies'          = array(),
        'menu_icon'           = 'dashicons-book-alt',
        'public'              = true,
        'show_ui'             = true,
        'show_in_menu'        = true,
        'menu_position'       = 6,
        'show_in_nav_menus'   = false,
        'publicly_queryable'  = true,
        'exclude_from_search' = false,
        'has_archive'         = true,
        'query_var'           = true,
        'can_export'          = true,
        'rewrite'             = array( 'slug' = 'ttest' ),
        'capability_type'     = 'post'
    ) );
}

add_action( 'init', 'ttest_register_cpt', 5 );

When the var_dump($actions); line is active I see the code dump in all the other default post types, even on the WooCommerce product post type, but not in my custom post type.

What am I doing wrong?
