Date column sorting not working for H24 format

Hello,
I use a simpleDateFormat "yyyy-MM-dd hh:mm:ss.SSS" to display a date in my datatable. I've to change this format to "yyyy-MM-dd HH:mm:ss.SSS" to have the 24H format.
But with this new format, the sort on date column is not working anymore, instead of a sort by date, it is doing an alphabetical sort. Although it was working with the previous format.
It is a matter of plugin I have to use or about code ?

This is my datatable :

$('#dataTables').DataTable({
    responsive: false,
    ajax: {
        "url": restURI + 'orch/search/events/',
        "contentType": "application/json",
        "type": "POST",
        "data": function ( d ) {
            return JSON.stringify(getDatasToSearch());
        },
        error: function(jqXHR, textStatus, errorThrown){
            manageAjaxError(jqXHR, textStatus, errorThrown)
        }
    },
    buttons: [
     'selectAll',
     'selectNone'
     ],
     language: {
         buttons: {
             selectAll: "Select all items",
             selectNone: "Select none"
         }
     },
     select: {
        selector: 'td:first-child',
        style: 'multi'
    },
    order: [0, 'desc'],
    scrollCollapse: true,
    scrollX: false,
    aLengthMenu: [
        [10, 25, 50, 100, -1],
        [10, 25, 50, 100, "All"]
    ],
    iDisplayLength: 25,
    "columns": [
        { "data": "EVENT_ID", "defaultContent": "", "sClass": "text-center limitedWidth" },
        { "data": "FLOW_ID", "defaultContent": "", "sClass": "text-center limitedWidth" },
        { "data": "FLOW_NAME", "defaultContent": "", "sClass": "text-center limitedWidthFlNm" },
        { "data": "OBJECT_TYPE", "defaultContent": "", "sClass": "text-center limitedWidth" },
        { "data": "OBJECT_NAME", "defaultContent": "", "sClass": "text-center limitedWidth" },
        { "data": "OBJECT_VERSION", "defaultContent": "", "sClass": "text-center limitedWidth" },
        { "data": "OBJECT_ITERATION", "defaultContent": "", "sClass": "text-center limitedWidth" },
        { "data": "OPERATION_NAME", "defaultContent": "", "sClass": "text-center limitedWidth" },
        { "data": "OPERATION_STATUS", "defaultContent": "", "sClass": "text-center limitedWidth" },
        { "data": "OPERATION_MESSAGE", "defaultContent": "", "sClass": "text-center limitedWidth" },
        { "data": "CREATE_DATE", "defaultContent": "", "sClass": "text-center limitedWidth","sType":"date" },
        { "data": "UPDATE_DATE", "defaultContent": "", "sClass": "text-center limitedWidth " ,"sType":"date" }
    ]
})

Thank you for your help !
