Sorting and Filtring Not working for ServerSide= true

HI All
Working with Datatable and serverSide= true and have filtering on all header columns every thing is working as accepted. Now i want to Add ordering on one of the column so add below code.
ordering: true,
order: [[8, 'desc']],
columnDefs: [
{
"orderable": true,
"targets": 8,
},
{
orderable: false,
targets: "no-sort"
}],

Ordering working separately but if i open my filter div which have checkboxes, when ever checking/unchecking it is making post call and then ordering my data. which is not expected.
Can any one help me out with this case.
