you have lost the ajax behaviour because you have modified the 

CartoWeb.trigger usualy accept 2 arguments

the first argument tell him what to do if ajax is enabled.
the second argument tell him what to do if ajax is disabled.

so, with CartoWeb.trigger('Outline.AddFeature', 'doSubmit()');, if ajax is 
enabled, it is the 'Outline.AddFeature' function which will be called. The 
'doSubmit()' is only there in case something is wrong and the whole page 
form is being sent in a "normal" way.

Outline.AddFeature basicaly call Ajaxhandler.buildPostRequest which call 
AjaxHelper.buildQueryFrom. This function get all the page input and try to 
get their value. The problem is the textarea elements are not input and 
hence have no value (this is not entirely correct but it is the usual 

So you need to modify a little bit the Outline.ajax.js to manually add the 
textarea value to the generated PostRequest.
something like:

    buildPostRequest: function(argObject) {
        var postRequest = AjaxHandler.buildPostRequest();
        postRequest += ''outline_label_text=' + 
        return postRequest

you can do an alert of postRequest to see its only a list of parameter name 
and their values param1=value1&param2=value2& ...
