List view in Hybrid App

Hello,

We are developing a Hybrid application.

In which, a screen has a listview, as per a BAPI result.

We tried to put a control field Button, below the listview in same screen.

But, after having button after the listview, we are not seeing the headers of the listview.

Also, the checkbox "Show header" has been grayed out, after putting the button.

Kindly help.

Thanks & Regards

Ajay
