Rails 3 remote form not triggering callback - ruby-on-rails

Question

I have a remote form that is populated by jQuery with an AJAX request. Then, I am binding this form to an AJAX callback but the callback is not being triggered.
var msgSuccess=function(evt, data, status, xhr){
alert('ok!!!');
console.log(evt);
console.log(data);
console.log(status);
console.log(xhr);
}
var bindMsg = function() { // BIND IT TO THE CALLBACKS
$("#composeMsgPopup")
.live('ajax:beforeSend', loadingCallback)
.live('ajax:success', msgSuccess)
.live('ajax:error', failureCallback)
.live('ajax:complete',completeCallback);
}
$.ajax({ // GETTING THE FORM CODE
url: link,
type: "get",
success: function(response, textStatus, jqXHR) {
ans=response;
$("#popup_content").html(ans);
$("#popup").bPopup();
bindMsg();
},
error: function(jqXHR, textStatus, errorThrown) {
failureCallback(errorThrown, textStatus, jqXHR);
},
complete: function(jqXHR, textStatus) {
completeCallback("", jqXHR, textStatus);
},
beforeSend: loadingCallback
});
The code for the form:
<%= form_for(:conversation, :remote => true,
:url=> {:controller=>:conversations,:action=>:create},
:html=>{:id => 'composeMsgPopup' }) do |f| %>
<div id="founder-name" class="field"><b>Recipient: <%= #user.name %></b></div>
<div class="field">
<%= f.label :subject,"Subject" %>
<%= f.text_field :subject,:class=>"composeMsgField" %>
</div>
<div class="field">
<%= f.label :content,"Message Content" %>
<%= f.text_area :content,:class=>"composeMsgField" %>
</div>
<%= f.hidden_field :to_user, :value => #user.id %>
<%= f.submit "Send", :class=>"submitbt",:id=>'sendMessage' %>
<% end % >
I have tried to bind with bind() or on() but it does not work. The code is executed but when I submit the form the callback is not executed.

Answer 1

ok i found a solution.
the remote form not triggering the callback for unknown reason, so what i did is change the
submit button behaviour:
<%= f.button :submit, "Update",:class=>"submitbt",:id=>"submitnewpass",:onclick=>"return false;" %>
and bind the button to manually submit the form
var action=$('#composeMsgPopup')[0].action; // action url
$("#sendMessage").click(function() { // bind submit button
$.ajax({
type: "POST",
url: action,
data: $("#submitnewpass").serialize(), // serializes the form's elements.
success: function(data)
{
// do my stuff
},
error: failureCallback,
beforeSend: loadingCallback,
complete: completeCallback
});
return false;
});
