Can't bind a table appropriately.

Hi,

I am developing a master-detail view. Once the detail view has retrieved the information from the master  view (When I select a entry) I want to create other view with a table where I want to display extra information of the entry that has been selected. The binding looks to be well written (the information of the first row is correct) but when I run the app the table generate more empty rows and I don't know how to fix it.

Now I have two entries so the table has two rows. If I run the app with mockdata, it's generate 100 entries and the table has 100 rows.

Here I attach the code and an image of the app.

If more code is needed to answer let me know and I'll attach it

Thanks in advance.
