Answer 1

Just change your ajax code.Controller is ok.
$("body").on('click', function(e) {
$.ajax({
type: "POST",
url: '<?=base_url("controller_name/function_name") ?>',
data: {name: "John",location:"Boston"},
success: function(response) {
alert("Data Saved: " + response);
}
});
});

Answer 2

Your data should be an object and remove .name. change that line in you ajax like this:
$("body").on('click', function(e) {
$.ajax({
type: "POST",
url: "response.php",
data: {name: "John",location:"Boston"},
success: function(msg) {
alert("Data Saved: " + msg);
}
});
});
