Splicing and then saving json array via ajax

I'm having trouble getting my json array to accept changes. I'm trying to remove an object from the array, and it appears to work but then when I look at the json array on the server it remains unchanged. What am I missing here?

Here is the function I'm using:

$(function() {
    $("#rectangle-delete").click(function() {

      var selection = $('#templateSelection > option:selected').text();

      var json = (function () {
        var json = null;
        $.ajax({
            'async': false,
            'global': false,
            'type': 'POST',
            'contentType':"application/json",
            'url': 'server/php/data/' + selection,
            'dataType': "json",
            'success': function (data) {
                json = data;
            }
        });
        return json;
      })();

      var ID_clicked = $(".rectangle.selected.targeted").attr('id');

      console.log('initial array is ' + json);

      json.some(function(e) {
        if (e.ID === ID_clicked) {

            var values = json.map(function(e) { return e.ID; });
            var index = json.map(function(e) { return e.ID; }).indexOf(ID_clicked);
            var data = JSON.stringify(json[index]);

            json.splice(index, 1);

            return true; // stop the array loop
        }
      });

      console.log('new array is ' + json);
    });
});

The console shows:

initial array is [object Object],[object Object],[object Object]

and then

new array is [object Object],[object Object]

but I'm still not changing the actual json file on the server.
