    $(document).ready(function () {
        $("#inputid").blur(function () {

It works for me, the issue is probably elsewhere, I've updated my answer to add more context.

JavaScript

var value = $("#inputid").val().trim();
           if (value == '')
           {
               alert("input should not be empty");
               $("#inputid").val('').focus();
               return false;
           }
