ColReorder - prevent fnServerData call

I am using the ColReorder plugin 1.0.8 with DataTables 1.9.2

My configuration is Server side processing, and I've noticed that when I drag a column to a new place, the fnServerData callback is fired. This results in re-executing the server side search. This is unnecessary, as the data itself is not changing. I tried to listen to the fnReorderCallback but it fires after the fnServerData callback.

I am handling the column-reorder event now to fix this. I was wondering if this behavior could be removed from ColReorder. Data should only be fetched on sorting/filtering/page requests...

I have attached my code here, minus the aoColumnDefs. (it's a 29 column table) As you can see, one thing I do is restrict the amount of data going to the server. 29 columns generates around 3k in the GET body. ouch!

self.grid_completedForms = $('#searchGridTable').dataTable({
                        "aoColumnDefs" :  null,//omitted for brevity

					if (oSettings.aaSorting.length) {
						dataToSend.push({ "name": "sortFieldName", "value": oSettings.aoColumns[oSettings.aaSorting[0][0]].mData });
						dataToSend.push({ "name": "sSortDir_0", "value": oSettings.aaSorting[0][1] });
					}

					dataToSend.push({ "name": "facilitySearch", "value": self.vm_facility.FIDN() });
					dataToSend.push({ "name": "incompleteForms", "value": self.input_checkIncompleteForms() });
