隐藏列共享点的下拉值无法正常工作，但在不同会话中一一选择值时它可以工作

Question

I used below code in share point 2013 for hiding the columns based on a value in a form. I have 3 conditions here but when i select one value it hides the columns, but in the same session if i select another value it will not hide the columns as expected instead it shows one or two columns. But when i select one value in one session it hides the columns and submit the form. can any one help me on below.

<script src="/business/49898/Request%20form%20library/jquery.min.js" type="text/javascript"></script><script src="/business/49898/Request%20form%20library/sputility.js" type="text/javascript"></script><script language="javascript" type="text/javascript">  
    $(document).change(function() 
    {  


        var studentType = SPUtility.GetSPField('Request Form Type');  


        var showOrHideField = function() {  
            var studentTypeValue = studentType.GetValue();  




              if (studentTypeValue == 'Tracking Number request') {  
                SPUtility.HideSPField('CSB Site Long Title');
    SPUtility.HideSPField('Opportunity Type');
    SPUtility.HideSPField('Sales Stage');
    SPUtility.HideSPField('Est. Close Date');
    SPUtility.HideSPField('Proposal Submission Date');

            }   

       if (studentTypeValue == 'Open project in PCB request') {  
                SPUtility.HideSPField('Secondary Unit Sales Rep/Business Unit name');

You just have hide logic, you need show the hided fields when option changes.

<script type="text/javascript" src="https://code.jquery.com/jquery-1.12.4.js"></script>

                if (studentTypeValue == 'Tracking Number request') {
