Getting properties of dojo's dijit.InlineEditBox for ajax request - dojo

Question

In essence I have the same problem as described in this question, but the accepted answer there is not fully working for me.
I want to have the id of the record I'm processing in an HTML5 compliant data-myid attribute, then when the text in the text area is changed, I want call a function that will send an ajax request containing the new value and data-myid to the server. This is important because there can be multiple inlineEditBoxesi a single page. The ajax request part I'm fine with, is getting the proper values to send where I'm stuck.
So far, I know the end result of the HTML declaration will look something like this:
<span data-dojo-type="dijit.InlineEditBox" data-dojo-props="editor:'dijit.form.Textarea'" data-myid="123" title="some title" id="test" >
<script type="dojo/connect" event="onChange" data-dojo-args="myid,value">
console.log(myid + " changed to value " + value);
</script>1339598</span>
But I have not been able to get this to work.

Answer 1

You can get the myId value through
this.domNode.dataset.myid;
... in your onChange event.

A more portable solution is to use dojo/dom-attr instead though, like this :
*HTML
<div id="editBox" data-dojo-type="dijit/InlineEditBox"
data-dojo-props="editor:'dijit/form/Textarea'"
data-myid="123"
title="some title">1339598</div>
<div id="output"><div>`
*Javascript :
require(["dojo/dom",
"dojo/dom-attr",
"dojo/parser",
"dojo/html",
"dijit/registry",
"dijit/InlineEditBox",
"dijit/form/Textarea",
"dojo/domReady!"],
function(dom, domAttr, parser, html, registry){
var editBox;
parser.parse().then(function(instances){
editBox = registry.byId("editBox");
editBox.on("change", function(value){
var myId = domAttr.get(this.domNode, "data-myid");
html.set(dom.byId("output"), "Editor " + myId + "'s value changed to " + value);
});
});
});
