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?
