If you need wait until user is finished with typing use simple this:

$(document).on('change','#PageSize', function () {
    //Do something after new value in #PageSize       
});

Complete Example with ajax call - this working for my pager - count of item per list:

$(document).ready(function () {
    $(document).on('change','#PageSize', function (e) {
        e.preventDefault();
        var page = 1;
        var pagesize = $("#PageSize").val();
        var q = $("#q").val();
        $.ajax({
            url: '@Url.Action("IndexAjax", "Materials", new { Area = "TenantManage" })',
            data: { q: q, pagesize: pagesize, page: page },
            type: 'post',
            datatype: "json",
            success: function (data) {
                $('#tablecontainer').html(data);
               // toastr.success('Pager has been changed', "Success!");
            },
            error: function (jqXHR, exception) {
                ShowErrorMessage(jqXHR, exception);
            }
        });  
    });
});
