DataTable export excel messup when search when colums containing select, input and editable div

 I have a table containing select, input and editable div in columns.
I have scripts to make export to EXCEL correctly in  DataTable  when  not using search box.
When using search box, exporting to EXCEL producing wrong  value.
I can not find a solution. Temporarily when in search mode, I hid the EXCEL button
as following:
                $('input[type="search"]').keyup(function(){

                   var search = $(this).val();                       
                   if(search.trim()=='')
                     $(".dt-buttons").show();
                   else
                     $(".dt-buttons").hide();

                  });
