Load More button inside ajax callback function

@dcooney nope, sorry for not being specific. I have a separate AJAX callback function that refreshes the container with displayed post links whenever the dropdown filter changes its value. This container also contains “Load More” button generated by your plugin. This button hides and stops functioning when i change the filter value and the AJAX call of my filter function is called. Please see my callback function:

<?php
add_action( 'wp_ajax_nopriv_filter', 'filter_ajax' );
add_action( 'wp_ajax_filter', 'filter_ajax' );

function filter_ajax() {

    $category = $_POST['category'];

    $post_type = 'my_post_type';
    $taxonomy = 'my_taxonomy';

    $posts_per_page = '10';
    $args = array(
        'post_type'   => $post_type,
        'post_status' => 'publish',
        'posts_per_page'=> $posts_per_page
    );

    if(isset($category) && $category !== "") {
        $args['tax_query'] = array(array ('taxonomy' => $taxonomy, 'field' => 'slug', 'terms' => $category,));
    }

    $articles = new WP_Query( $args );
    if( $articles->have_posts() ) :
        ?>

        <div class="columns">
            <?php
            while( $articles->have_posts() ) :
                $articles->the_post();
                ?>

                <div class="article-box column">

                    <a href="<?php echo get_the_permalink() ?>">
                        <div class="box">

                            <h4>
                                <?php
                                $categories = get_the_terms($post, $taxonomy);
                                if (!empty($categories)) {
                                    echo esc_html($categories[0]->name);
                                }
                                ?>
                            </h4>
                            <p><?php echo get_the_title() ?></p>
                        </div>
                    </a>
                </div>

            <?php
            endwhile;
            echo do_shortcode('[ajax_load_more container_type="div" post_type="'.$post_type.'" taxonomy="'.$taxonomy.'" taxonomy_terms="'.$category.'" taxonomy_operator="IN" posts_per_page="'.$posts_per_page.'" pause="true" scroll="false" transition_container="false" button_label="Show More" offset="'.$posts_per_page.'" orderby="menu_order"]');
            ?>
        </div>
    <?php
    else :
        esc_html_e( 'No Articles found!', 'text-domain' );
    endif;
    wp_reset_postdata();
    die();
}

Please note that im a total noob in ajax and this is my first ever callback function

It did the magic, thanks a million!:)
