If you look at the Form documentation, you will see that the Submit event fires at the end of the submission - after any values from form fields have been put into your TestPojo's. Therefore, you are wiping out any changes at the end of your submit.
You could set up the list in onPrepare(). Just make sure not to re-initialized it unless that's what you really want.
