How to reload/refresh jQuery dataTable?

Question

I am trying to implement functionality whereby clicking a button on the screen will cause my jQuery dataTable to refresh (as the server-side data source may have changed since the dataTable was created).

Here's what I have:

$(document).ready(function() {
    $("#my-button").click(function() {
        $("#my-datatable").dataTable().fnReloadAjax();
    });
});

But when I run this, it does nothing. What's the proper way to refresh the dataTable when the button is clicked? Thanks in advance!

According to the DataTable help, I could done for my table.

I want wanted multiple database to my DataTable.

For example: data_1.json > 2500 records - data_2.json > 300 records - data_3.json > 10265 records

var table;
var isTableCreated= false;

if (isTableCreated==true) {
    table.destroy();
    $('#Table').empty(); // empty in case the columns change
}
else
    i++;

table = $('#Table').DataTable({
        "processing": true,
        "serverSide": true,
        "ordering": false,
        "searching": false,
        "ajax": {
            "url": 'url',
            "type": "POST",
            "draw": 1,
            "data": function (data) {
                data.pageNumber = (data.start / data.length);
            },
            "dataFilter": function (data) {
                return JSON.stringify(data);
            },
            "dataSrc": function (data) {
                if (data.length > 0) {
                    data.recordsTotal = data[0].result_count;
                    data.recordsFiltered = data[0].result_count;
                    return data;
                }
                else
                    return "";
            },

            "error": function (xhr, error, thrown) {
                alert(thrown.message)
            }
        },
        columns: [
           { data: 'column_1' },
           { data: 'column_2' },
           { data: 'column_3' },
           { data: 'column_4' },
           { data: 'column_5' }
        ]
    });
