Issue with Access PHP array in display module

Question

I am passing few parameters via ajax to custom module (fgs_api.module) and in returns getting JSON data ($results->data). I want to use/get that variable ($results->data) in node--xyz.tpl.php content template. How can I use that variable in node--xyz.tpl.php. I am doing in drupal 7.

In module fgs_api.module

function fgs_api_data_execute($parameter1, $parameter2)
{   
    if(!is_null($parameter1) && !is_null($parameter2))
    {
        // my custom code which is working
         $results = $api->{'getSpecialOfferHomes'}(intval($parameter1), intval($parameter2)); 

        if($results->success)
        {
            $return = fgs_api_format_return(false, $results->data);
        }else{
            $return = fgs_api_format_return(true, $results->message);
        }
    }else{
        $return = fgs_api_format_return(true, 'Incorrect parameters');
    }
    return $return;
}

In Js

  var url = '/fgs_api_data_execute/' + parameter1 + '/' + parameter2;    
                console.log(url);

                $.ajax({
                    url: url,
                    type: 'POST',
                    dataType: 'json',
                    success: function (result) {   
                        if (result.data) {
                             console.log(result['data']);  // use this data in Module           
                        }else {
                           console.log("error");
                        }
                    },

How can I use/pass return data variable from custom module to node--xyz.tpl.php?
