Hi @Jagadis,

Event handlers in the form itself will not work on the Portal, they work only inside model-driven apps. You would need to add on change triggers in the Custom Javascript section of the form. Your code would look something like this:

$(document).ready(function () {
 // id of the field is its logical name

function onTitleChange() {
 console.log("My title changed");

You can find more about working with Javascript for portal in this official doc. In general, I would advise you to google example on using code specifically on entity forms as code design to work inside dataverse won't work on the portal.

Its done often - as per the previous posts. 

Not, sure if it is still the case but we came across an issue for an Entity Form popup (actually inline) rather than on a Web Page, where we had to change the (document).ready to another keyword than 'ready'.
