I am currently getting an error 'Unknown property 'Feature_Request__cStandardController.ofrJO'' on a visualforce page I am trying to implement. I followed a design I had from a wrapper class that worked for me prior but in this case I only want to have the command button be on a specific line. I don't think this is the issue but I would really love some help from the community on resolving the issue. Thanks in advance!

Visualforce Page:
 

<apex:page StandardController="Feature_Request__c" extensions="FeatReqOppJunctionExtension">

        <apex:stylesheet value="//cdn.datatables.net/1.10.4/css/jquery.dataTables.css" />
        <script>
            j$ = jQuery.noConflict();
            j$(document).ready( function () {
                var contactTable = j$('[id$="table"]').DataTable({
                    
                });
            });
    </script>
