Hello Victor,

Thank you for reporting this issue, we managed to replicate this with a very simplified markup and the issue seems to be caused by the fact that the <span> elements inside the button do not propagate the click event properly.

As a temporary workaround, you can use the following script:

<script>
    var $ = $ || $telerik.$;
    $(document).ready(function () {
        $("body").on("click", ".RadDataPager button > span", function (ev) {
            ev.preventDefault();
            $(this).closest("button")[0].click();
        })
    });
</script>

Also, as a token of gratitude for helping us identify the issue, I have updated your Telerik points.

Regards,
Peter Milchev
