The 4 things I see on your snapshot look like the 4 rows of the Items table, but your app only searches from the List_r table.
I also see that your app does a search from the code inside the ItemTemplate2 template.
The correct way to use databinding with a repeating panel is to create a list of dictionaries and assign it to items of the repeating panel. The repeating panel will take care of assigning each dictionary from the list to one instance of its template form. In simple cases like this you don’t need any code in the template form.
Try to follow the tutorial linked here. It’s old, but it’s still a good way to understand what the databinding does with a repeating panel and the template forms contained in it.
