TinyMCE - Custom plugin makes visual editor blank in wordpress

Question

I am trying to add TinyMCE custom plugin in wordpress that change the direction of selected text by using <bdo>. I register the plugin in wordpress:

/*Register Custom TinyMCE plugin*/
add_filter('mce_external_plugins', 'my_tinymce_plugins');

function my_tinymce_plugins() {
  $plugins_array = array(
    'tiny' => 'tiny.js' //Plugin directory is same as theme's funtion.php
  );
  return $plugins_array;
}

But it hide visual editor completely & also make text editor, un-editable. What is wrong?

I think you're overwriting all the other plugins, rather than just adding yours. Try

function my_tinymce_plugins($plugin_array) {
    $plugin_array['tiny'] = 'tiny.js';
    return $plugin_array;
}

instead. You may need to prepend get_stylesheet_directory_uri() to tiny.js to ensure the URL is correct.

Edit

Further to your comment, here's some code I used a few years ago to add a button. I can't say for certain best practices haven't changed, but it worked for me:

add_action('init', 'immo_add_column_button');
function immo_add_column_button() {
    if ( ! current_user_can('edit_posts') && ! current_user_can('edit_pages') ) {
        return;
    }
    if ( get_user_option('rich_editing') == 'true') {
        add_filter('mce_external_plugins', 'immo_add_column_tinymce_plugin');
        add_filter('mce_buttons', 'immo_register_addcolumn_button');
    }
}

function immo_register_addcolumn_button($buttons) {
    array_push($buttons, "|", "addcol");
    return $buttons;
}

function immo_add_column_tinymce_plugin($plugin_array) {
    $plugin_array['addcol'] = get_bloginfo('stylesheet_directory').'/js/immo_column_button.js';
    return $plugin_array;
}

add_filter( 'tiny_mce_version', 'immo_refresh_mce');
function immo_refresh_mce($ver) {
    // Force refresh of TinyMCE cache by updating the version number
    $ver += 3;
    return $ver;
}
