Pass generated javaScript code to another page inside the script tag

I have two functions one prepares the data and makes a call to Ajax and within the call to Ajax has a callback to another function. As per the code below:

function retorno_pizza_nacionalidade(result){
console.log(result);
}

function grafico_pizza_nacionalidade(){
var dados = "typepost=grafico_pizza_nacionalidade";

AjaxExecute("php/main_index.php", dados, retorno_pizza_nacionalidade, erro);
}

This all works perfectly, the problem is that I need to pass the return of the function return_pizza_nationality into the tag that is on my index.php page how can I do this with javascript or JQuery. I researched a lot, but I did not find anything like that. Below the return I need to "paste" inside the tag. Thanks in advance.

$(function () {
            Highcharts.chart('pie', {

                    plotBackgroundColor: null,
                    plotBorderWidth: null,
