ajax.reload does not reload?

I tried to modify data content in local exercise_data.json file but nothing happens..

$(document).ready(function() {
    var table = $('#example').dataTable( {
        "ajax": {
            "url": "exercise_data.json",
            "dataSrc": ""
        },
        "columns": [
            { "data": "name" },
            { "data": "city" },
            { "data": "country" },
            { "data": "company" },
            { "data": "job_history" },
            { "data": "email" }
        ]
    } );

    //https://datatables.net/reference/api/ajax.reload
    setInterval(function () {
        table.ajax.reload(null, false);
    }, 3000);

   //also tried this and also doesn't work - reload is a button on HTML page
    $('#reload').click(function () {
        table.ajax.reload(function(data){
            console.log(data);
        }, false);
    } );

   //also tried
   table.ajax.reload();
} );

Or a better way to test the functionality is to generate a random set of numbers so that these changes are automatically passed and refreshed in dataTable?

Anyone?
