Triggering elect Event of sap.m.table

Hi Experts, I have an issue with triggering select event of an sap.m.table. I have defined a table as follows :

I get a table with 1 entry as result after callin an odata service. The first time when i select the item from the table , the navigation to the details screen works fine. From the details screen i go back to the the table screen. After that : every time i try again to navigate to the details screen, the selet event is not triggered. I put a break inside the method onSelectOrder : no succes. Anybody has some tips/suggestions? Thanks in advance, Regards, Moo
