I'm working on writing an app using the 3.18 version API and there appears to be a notification for Chrome (and a resulting no-show on IE 11) for the portion relating to the dijit text box. Here is the specific notification I'm getting:

From what I can tell, this is pertaining to the JS file from the API. Is there something else I should be using for the text entry in the text box. As a reference, here is the code I'm referring to:
on(dijit.byId("stringTextBox"), 'change', function(value){
var userVal = dijit.byId("stringTextBox").get('value');
