Dynamic Field not taking multiple inputs

Hello, 

I'm trying to use a dynamic field to allow users to add more text inputs for email addresses. Currently, the email address fields all show whatever the most recent text added is--only showing the same email address in all of the boxes.

 What am I doing wrong? Thank you for any help.

              {
                a!columnsLayout(
                  columns: a!columnLayout(
                    contents: {
                      a!richTextDisplayField(
                        labelPosition: "COLLAPSED",
                        value: {
                          a!richTextItem(
                            text: "Notification Recipients",
                            style: "STRONG"
                          )
                        }
                      ),
                      a!forEach(
                        items: local!emailNotify,
                        expression: {
                          a!sideBySideLayout(
                            items: {
