How to put the cursor in standby mode in visual basic.net?

I'm making the pointer change it changes to "wait" with javascript and I do not have any errors. When I run my program if I get to execute my javascript code, but the results are not displayed. I do not know what may be happening, I've had problems like that before. Thank you in advance to help me.

My archivo "cursor.js"

$(document).ready(function () {

  $("#btnTerminar").submit(function () {

    $("body").css('cursor', 'wait');

      setInterval(function () { $("body").css('cursor', 'auto'); }, 3000);

  });

});
