Jquery Jtable load Json from ajax call

I am using jtable.org-s library for showing rows in a table. For populating rows I used listAction like this:

actions: {
  listAction: '/Passengers/Search'
},

This URL returned valid json and everything worked fine. But I want to call the URL manually from ajax, because this URL returns more info than rows. It also returns info I need for other form elements, such as search result items count, woman/man ratio and etc.

So, I want to ajax call, and load the response to my jtable:

$.ajax({
  url: '/Passengers/Search',
  type: 'POST',
  data: {},
  success: function(data) {
    // here I would like to inject the Json(data) to my table
  }
});

You can use FunctionsAsActions feature of jquery-jtable.
In ajax success filter you can filter your response data and by using $dfd.resolve(data); you can load filtered data to jquery-jtable.
For example:

listAction: function (postData, jtParams) {
                    console.log("Loading from custom function...");
                    return $.Deferred(function ($dfd) {
                        $.ajax({
                            url: '/Demo/StudentList?jtStartIndex=' + jtParams.jtStartIndex + '&jtPageSize=' + jtParams.jtPageSize + '&jtSorting=' + jtParams.jtSorting,
                            type: 'POST',
                            dataType: 'json',
                            data: postData,
                            success: function (data) {
                                //filter your data here and then pass filtered data to $dfd.resolve function

                                $dfd.resolve(data);
                            },
                            error: function () {
                                $dfd.reject();
                            }
                        });
                    });
                },
