How to get a text / return(JSON ) in my API code with Watson? - node.js

Question

In my example,
If the user clicks the button "Yes" Will return a conversation text. But I'd like it to return a value from my output, the return from my AJAX Post example, which is currently only coming from the "alert (output.request.number)".
How to make? Follow the codes:
In the conversation Intents: #goodbye and two entities: #goodbye:yes and #goodbye:no. If my client-side recognize the intent and user clicks the button "yes", will return something.
My JSON Advanced (Conversation Service)
{
"output": {
"text": "You can finish the conversation? \n \n
<button id=\"button-yes\" onclick=\"OneFunction();\">Yes</button>
<button id=\"button-no\" onclick=\"OtherFunction();\">No</button>"
}
}
I need the return of alert(output.request.number) to come in Watson's conversation flows if the user clicks on the button.
The JS code:
function OneFunction(firstParameter, secondParameter){
console.log(firstParameter);
$.ajax({
type: 'POST',
dataType: 'json',
contentType: "application/json",
url: 'http://xxxxxxxxxxxxxxxxxxxxxxxx/request/create',
data: JSON.stringify({
"dataOne":firstParameter,
"synchronize":false,
}
}),
success:function(output, input, response) {
console.log(output);
// alert(output.request.number);
var responseText = null;
var outputTest = {};
outputTest = output.request.number;
var latestResponse = Api.getResponsePayload();
// console.log(latestResponse);
var context = latestResponse.context;
Api.sendRequest = ("Yes", + outputTest); // THIS RETURN one number of request
}

I try it and work, the error is just a , between ("Yes" + outputTest);
But yours information was essential to this, thanks, #Michal Bida and #timd. :
success:function(output, input, response) {
console.log(output);
// alert(output.request.number);
var responseText = null;
var outputTest = {};
outputTest = output.request.number;
var latestResponse = Api.getResponsePayload();
// console.log(latestResponse);
var context = latestResponse.context;
Api.sendRequest = ("Yes" + outputTest); // THIS RETURN one number of request
