Listview remove the input field label if try to add new item on it

I build a listview and an input field inside it and when I try to add a new item(input field) on the same list, it removes the input fields' label.

there is a listview name arrayListView and there is an input field (childTextElements label name element) it has two buttons to add and remove an item from listview, when try to add an item it removes the labels.
