On Creation - refresh the page / datatable

Happy Evening All,

Following is the code used to create, edit and delete inside a datatable. Looking at adding refresh option to the page/table every time when create button is used. Tried following code no result, any help would be grateful.

Code used to create:

var table = $('#issue_manager').DataTable( {
        dom: 'Bfrtip',
        ajax: 'DataTablesEditor/php/table.issue_manager.php',
        columns: [
            {
                "data": "iss_no"
            },
            {
                "data": "iss_summary"
            },
            {
                "data": "iss_description"
            },
            {
                "data": "iss_staus"
            },
            {
                "data": "iss_raised_by"
            },
            {
                "data": "iss_raised_by"
            },
            {
                "data": "iss_last_update"
            },
            {
                "data": "iss_assigned"
            }
        ],
        select: true,
        lengthChange: false,
        buttons: [
            { extend: 'create', editor: editor },
            { extend: 'edit',   editor: editor },
            { extend: 'remove', editor: editor }
        ]
    } );

Option 1

$(document).on('click', '#refreshdates', function(dn) {
        $('#issue_manager').DataTable().ajax.reload();
        });
 
    $(document).on('click', '#cleardates', function(dn) {
        $('#startdate').val("");
        $('#enddate').val("");
        $('#issue_manager').DataTable().ajax.reload();
    });

Option 2

$('#issue_manager').DataTable().ajax.reload();

Also, I am not sure on how and where to place this code, so that it will get execute when 'create' button is used.
