Post view not showing – Postviews plugin

I have added this code
`<?php
add_action( ‘generate_after_post_meta’, ‘tu_post_views’, 15 );
function tu_post_views() {
if ( is_single() ) {
echo do_shortcode( ‘[post-views]’ );
}
}?> `

to my content-single.php file but nothing is showing. See what I am trying to achieve here.

See more of the codes below, my breadrumb was set to display before post_meta

		<?php
			/**
			 * generate_before_entry_post_meta.
			 *
			 * @since 0.1
			 */
			do_action( 'generate_before_post_meta' );?>
			<div class="breadcrumbs" typeof="BreadcrumbList" vocab="http://schema.org/">
			<?php if(function_exists('bcn_display'))
    {
        bcn_display();
    }?>
</div>
			<?php
			/**
			 * generate_after_entry_title hook.
			 *
			 * @since 0.1
			 *
			 * @hooked generate_post_meta - 10
			 */
			do_action( 'generate_after_entry_title' );
			?>
			
			<?php
			add_action( 'generate_after_post_meta', 'tu_post_views', 15 );
function tu_post_views() {
    if ( is_single() ) {
        echo do_shortcode( '[post-views]' );
    }
}?>
