Yii2 Why does pjax reload the page when sorting a column and removing (ActionColumn)?

Question

Yii

The page is reloaded in 2 cases: when sorting and when clicking in the ActionColumn (delete icon)

view:

<?php
$js = <<< JS
var path = location.href.replace(location.hash,"");
jQuery(function(){
    var loc = window.location.hash.replace("#","");
    if (loc!="")
        {
            /*$('.tab-pane').each(function(){
                $(this).removeClass('active').removeClass('show');
            });
            $('.nav-item').each(function(){
                $(this).removeClass('active');
            });
            $('.nav-item[href=\"#'+loc+'\"]').addClass('active');
            $('#'+loc).addClass('active').addClass('show');
            console.log('.nav-item[href=\"#'+loc+'\"]');
            console.log($('.nav-item[href=\"#'+loc+'\"]'));*/
            $('.nav-item[href=\"#'+loc+'\"]').click();
        }
        jQuery('#nav-tab li:last-child a').tab('show');
        jQuery('#nav-tab .nav-item').on('click',function(){
            location.href = path + jQuery(this).attr("href");
        });
    });
JS;

$this->registerJs( $js, $position = yii\web\View::POS_READY, $key = null );
?>​
