File export using DataTables plugin - can't display the button

I need to use DataTable plugin to export data do CSV. I've already added JS and CSS libraries by documentation: https://datatables.net/extensions/buttons/examples/initialisation/export.html

I've tried to use direct urls to JS and CSS files and also tried to copy the files to local folders. But I still can't display the export button...

@using System.Web.Optimization
@model List<Gui.Models.AlarmReceiverModel>

@{
    ViewBag.Title = @Html.Translate("Global", "AlarmReceiver");
}

<!-- Bootstrap core CSS -->
@Styles.Render("~/Content/cssConti")

<!-- test -->
