Event history after .request.post

Hello. Help, please.

I get a next page using app.request.post in success function section.

<template>
...
</template>
<script>
return {
    on: {
      pageInit: function () {
        app.request.post('php/request_list.php', {dates: '...' }, function (data) {
          $$('td').on ('click', function () {

            app.router.navigate('/request/');

          });  
        });
      },
 }
}
</script>

when returning, the previous page stops reacting to the “back” button. (?)
in routes:

    path: '/request_list/',
    componentUrl: './pages/request_list.html',

Thanks

Ooops… index file is .php, change to index.html
