Similar problem even using a switch. It doesn’t trigger the item click event and it switch value of ALL switches at a time.  
However, maybe it’s better to discuss it on teh specific topic

For now, it seems there is no way to scan items of a list out of a Data Source scanning and using a boolean object so I MUST insert the “boolean” value in the data source table and display it as a label.
