Liferay 7.2 - Change liferay-ui:input-localized XML with javascript

Hello,
I have already posted this on StackOverflow, and I am really trying to get this working, but I could not manage it yet. So I am posting this here with the hope that someone knows how to do this.
I have the following tag in my view.jsp:
And I know that I can set a XML and have a default value on my input localized. My problem is that I want to change this attribute with javascript. I am listening for some changes and call the function "update()" to update my information:
Changing the value is only updating the currently selected language input (with the whole XML String). The XML String is correct, but I am not sure on how to update the XML for the input with javascript.Is this possible?

I have the following tag in my view.jsp:
<liferay-ui:input-localized id="message" name="message" xml="" />
And I know that I can set a XML and have a default value on my input localized. My problem is that I want to change this attribute with javascript. I am listening for some changes and call the function "update()" to update my information:
function update(index) {
var localizedInput= document.getElementById('message');
localizedInput.value = 'myXMLString';
}
Changing the value is only updating the currently selected language input (with the whole XML String). The XML String is correct, but I am not sure on how to update the XML for the input with javascript.Is this possible?

I found a workaround that I will be quoting from my response in StackOverflow:
After a week of studying the case and some tests, I think that I found a workaround for this. Not sure if this is the correct approach, but it is working for me so I will post my current solution for future reference.
After inspecting the HTML, I noticed that the liferay-ui:input-localized tag creates a input tag by default, and then one more input tag for each language, each time you select a new language. Knowing that, I created some functions with Javascript to help me update the inputs created from my liferay-ui:input-localized. Here is the relevant code:
With this I am able to update the liferay-ui:input-localized inputs according to a pre-built XML String. I hope that someone finds this useful and if you have anything to add, please let me know!

function updateAnnouncementInformation(index) {
var announcement = announcements[index];
// the announcement['message'] is a XML String
updateInputLocalized('message', announcement['message']);
}
function updateInputLocalized(input, message) {
var inputId = '<portlet:namespace />' + input;
var xml = $.parseXML(message);
var inputCurrent = document.getElementById(inputId);
var selectedLanguage = getSelectedLanguage(inputId);
var inputPT = document.getElementById(inputId + '_pt_PT');
inputPT.value = $(xml).find("Title[language-id='pt_PT']").text();
var inputEN = document.getElementById(inputId + '_en_US');
if (inputEN !== null) inputEN.value = $(xml).find("Title[language-id='en_US']").text();
else waitForElement(inputId + '_en_US', inputCurrent, inputId, xml);
var inputLabel = getInputLabel(inputId);
if (selectedLanguage == 'pt-PT') inputLabel.innerHTML = '';
else inputLabel.innerHTML = inputPT.value;
if (selectedLanguage == 'pt-PT') inputCurrent.value = inputPT.value;
else if (inputEN !== null) inputCurrent.value = inputEN.value;
else waitForElement(inputId + '_en_US', inputCurrent, inputId, xml);
}
function getSelectedLanguage(inputId) {
var languageContainer = document.getElementById('<portlet:namespace />' + inputId + 'Menu');
return languageContainer.getElementsByClassName('btn-section')[0].innerHTML;
}
function getInputLabel(inputId) {
var boundingBoxContainer = document.getElementById(inputId + 'BoundingBox').parentElement;
return boundingBoxContainer.getElementsByClassName('form-text')[0];
}
function waitForElement(elementId, inputCurrent, inputId, xml) {
window.setTimeout(function() {
var element = document.getElementById(elementId);
if (element) elementCreated(element, inputCurrent, inputId, xml);
else waitForElement(elementId, inputCurrent, inputId, xml);
}, 500);
}
function elementCreated(inputEN, inputCurrent, inputId, xml) {
inputEN.value = $(xml).find("Title[language-id='en_US']").text();
var selectedLanguage = getSelectedLanguage(inputId);
if (selectedLanguage == 'en-US') inputCurrent.value = inputEN.value;
}
With this I am able to update the liferay-ui:input-localized inputs according to a pre-built XML String. I hope that someone finds this useful and if you have anything to add, please let me know!
