rails 3 - ajax form ajax:success event not being called

Question

After much troubleshooting, I am not able to figure out why my form's ajax:success callback is not being called in rails 3.

Following is the code ultimately generated in my view:

JS Code:

$(function() {
  $("#myform").bind('ajax:success', function(data, status, xhr) {
    alert("form success");
    console.log(data);
    console.log(status);
  }).bind('ajax:error', function(xhr, status, error) {
    console.log(error);
    console.log(status);
  });
});

Ajax Form:

<form accept-charset="UTF-8" action="/myc/mya" data-remote="true" id="myform" method="post">       <div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" /><input name="authenticity_token" type="hidden" value="hZuhxwboQj2qo8MPIR8DWwYMqAC1V2yqG+DX9UnlIr0=" /></div>
          <input class="large" id="foo" name="foo" type="text" />
        <input class="btn success" data-disable-with="Working..." name="commit" type="submit" />
        </form>

Following the logic that happens in the action which the form posts to:

 @foo = { :foo => "bar" }
 render(:json => @foo.to_json, :content_type => 'application/json',
        :layout => false)

I have Firebugged this entire request/response:

It says 200 OK. And the Response Headers are:

Cache-Control   max-age=0, private, must-revalidate
Connection  Keep-Alive
Content-Length  13
Content-Type    application/json; charset=utf-8

The response is, as expected:

{"foo":"bar"}

200 OK response should trigger 'ajax:success' in my JS... but this is not happening. Any thoughts? The error callback is not being hit either...

I had this same issue. After 90 minutes of searching I finally got it to work by using the following:

$(document).on('ajax:success', '.delete', function(e) {
    $(e.currentTarget).closest('div').fadeOut();
});
