Dropdown field in Table view - Change&Save simoultaneously

Hello, CCv6 Guru,
I have a table view with simple Dropdown field:
​

​
The Question is - what should I do to have this Dropdown Save the value when changed? Without any other button , action, etc? Is it possible?
​
This is what I have so far:
​
1) Created Dropdown with FieldName - Statuss[rekStat] and Dropdown view name - rekina_statuss ;
2) Added Dropdown to the Table Columns views - Submission.rekStat:{view:rekina_statuss}
3) Created Save function save_data_statuss with

1. Data Provider {data:Statuss},
2. Data override rekStat:{data:rekStat} on insert&update;
3. Condition Submission.aid={data:aid}

4) tried to add this function to Dropdown Event - did not suceed...
​
What should I do to make this work? To save the changed option of that dropdown field as soon as it has been changed?
​
Should I need PHP function added or I can do that with built-in CCv6 possibilities?
Thanks!
