How can I add the data to jquery DataTable as dynamically?

I use the DataTable version 1.10. I want to add to table as dynamically? I know that need to use the table.push() method for this. But I don't know how can I use the table.push() method in my project . Is there anyone help me for this regard.

I do like this:

        var body = '<tr>';
        body += '<td>' +
        '<div class="img-container">' +
        '<img src="../../assets/img/room-plan/' + r_plan + '" alt="..." id="imgsrc">' +
        '</div>' +
        '</td>';
        body += '<td id="imgname">' + r_name + '</td>';
        body += '<td class="text-right">' +
        '<a href="#" class="btn btn-simple btn-warning btn-icon edit" data-toggle="modal" data-target="#myModal"><i class="fa fa-edit"></i></a>' +
        '<a href="#" class="btn btn-simple btn-danger btn-icon remove" ><i class="fa fa-times"></i></a>' +
        '</td>';
        body += '</tr>';

        $('#datatables').dataTable().fnDestroy();

        $(body).appendTo($("tbody"));
           // $('#datatables').dataTable();

        var table = $('#datatables').DataTable({
            "pagingType": "full_numbers",
            "lengthMenu": [[10, 25, 50, -1], [10, 25, 50, "All"]],
            responsive: true,
            language: {
                search: "_INPUT_",
                searchPlaceholder: "Search records",
                //"zeroRecords": " "
            }

        });

        table.push(body);

What is the problem in here?
