title: loading data in datatable on onchange event
body: <p>I want to implement function in which data will be loaded into datatable after onChange event. So for that I am trying to implement code as below.</p>
  
  <pre><code>var viewdatatab  =  $('#dataTablesFeedback').dataTable({                    
  
                  "columns": [
  
                      { "data": "resourceId" },
                      { "data": "feedbackRecommendation" },
                      { "data": "technicalSkillGaps" },
                      { "data": "technicalAvgSkills" },
                      { "data": "feedbackType" },
                      { "data": "feedbackId" },
                      { "data": "isNew" },
  
                  ]
          }); 
  </code></pre>
  
  <p>Which is creating my datatable layout and I am calling below function on dropdown change event is :</p>
  
  <pre><code>function loadFeedback(){
  
  viewdatatabJS  =    $('#dataTablesFeedback').dataTable({                    
       "processing" : true,
       "retrieve" : true,
      "ajax" : "/nhp/rest/feedback/viewFeedback",
      "fnServerParams": function ( aoData ) {
         aoData.push( { "name": "userName", "value":employeeId } ,
                      { "name": "resourceId", "value":mentorDataJson[$('#dropDownId').val()].resourceId });
       }, 
  });
  }
  </code></pre>
  
  <p>Where I am passing some parameter in aoData.push but my URL is not getting called.</p>
