How to call Text Field using a 'Date' type as a value?

As you can see by looking at the file, click the Add button, enter the information in the popup, and click the Add button to become Add Rows in the Repeater.
However, Date of Birth cannot be entered. The text field used here seems to be using a type called ‘Date’. Is there any way to call it as a value?
(Birth format is not necessarily “YYYY/MM/DD” format.)

Additionally, when clicking the first Add button, the function to reset the value of the text field in the popup to blank does not work too.
