Combo box backed by an Array shows value and not display value on adding new row

Summary

Combo box backed by an Array shows value and not display value

Content

I have combo box shown in a custom Template inside oj-bind-for-each tag

When I choose the first row's combo box, it shows the display value correctly.

When I add a new row in the array, the first row's combo box starts showing the value and not the display value

Could you please help here?
