To work with ajax, a plugin needs :

in php ClientYourpugin.php:

ajaxGetPluginResponse(..) to return the templates via ajax
ajaxHandleAction(..) to react to actions sent via ajax

in javascript Yourpugin.ajax.js

AjaxPlugins.Yourpugin = {

handleResponse: function(pluginOutput) {
... // to handle the template returned via ajax, you usualy call the 
AjaxHandler.updateDomElement function to place the template at the right 


AjaxPlugins.Yourpugin.Actions = {};

AjaxPlugins.Yourpugin.Actions.Someaction = {

    // this is an action called from a button or javascript link in your 
template, usualy with an onclick="return 
CartoWeb.trigger('Yourpugin.Someaction', 'doSubmit()');"

    buildPostRequest: function(argObject) {
        return AjaxHandler.buildPostRequest(); // unless you want to return 
some specific variable

look at plugin Outline, it has all these functions
