Datepicker icon trigger not displaying

Datepicker icon trigger not displaying

I have a ASP.Net MVC 5 project. I am trying to use the datepicker with an icon trigger.
I know the jQuery UI 1.11.1 NuGet package changed the naming for the CSS files.

I have the datepicker displaying correctly.
However, my issue is the icon is not displaying.




$('#datepicker').datepicker({
  showOn: "button",
  buttonImage: "images/calendar.gif",
  buttonImageOnly: true,
  buttonText: "Select date"
});
