Progress Status update page

Please am trying to create a progress status page build with data assist. Everything works fine apart from the update page. What am trying to achieve is that I have progress page where i can click on a record and update user with the current info. Like when i click the update for a record set i can enter a progress - like new location of parcel without overriding the previous update. Basically if I've update the info at 12:00pm with new location london, when i click on update of that record set again i should be able to enter 2:00pm new location kent, without overriding the firsts record since the list of the progress is being view by the client. Please how can i achieve this cause i have the update form and the current status form on the same page.

So far it works when i insert the new info to the form, i can see it in the database but the new updated info is not showing on the update page, although i bind it to that page but it doesn't show but am not sure why it's not showing but i can see the new info inside the database

Your help is much appreciated. Here is link to the testing site.
