How to run swipper on ajax request?

Question

AJAX

There is a slider from the titles of the posts by clicking on the title of the post, an ajax request is made and the data of the post
is displayed. This data is presented as a slider (Main photo + thumbnail).

I used Swipper slider, when getting response to ajax request, the content appears but the slider doesn't start. Moreover, the slider works without ajax loading, I tried to shove the launch of the slider into ajax, but it doesn’t work, I also wrote observe: true doesn’t help either, here’s the code:

function fetch(e){var param = $(e.target).attr('data-ajax-param');
  // Находим id поста по нажатию кнопки. У кнопки должен быть атрибут data-ajax-param равный id поста, например, data-ajax-param="11"
  $.post('https://dzenfood.by/wp-admin/admin-ajax.php', {'action':'my_action', 'param':param}, function(response){
  $('.modal-content.ajax').html(response);
    var swiperrr4 = new Swiper(".mySwiperrr4", {
      loop: false,
      spaceBetween: 10,
      freeMode: true,
      observer:true,
      observeParents:true,
      allowTouchMove: false,
      watchSlidesProgress: true,
    });
    var swiperrr3 = new Swiper(".mySwiperrr3", {
      loop: false,
      allowTouchMove: false,
      spaceBetween: 10,
      navigation: {
        nextEl: ".swiper-button-next3",
        prevEl: ".swiper-button-prev3",
      },
      thumbs: {
        swiper: swiperrr4,
      },
      observer:true,
      observeParents:true,
    });
});
}

  $( '[data-ajax-param]' ).click(function (e) {
  fetch(e);
});

It works, but the launch of the slider does not work.

Here is the content output code

$recent = new WP_Query($args);

    while ( $recent->have_posts() ) : $recent->the_post();?>

        <div class="two-sliders two-sliders1 two-sliders1--active" id="tab-time1">

    <?php endwhile; ?>
<?php

}
