Select the listbox using jQuery is not saving the result

Question

I am using jQuery and SpServices to add some preferred item in a multi select lookup field.

Based upon the select on top i prefill this multi select list and it worked well.

The problem is when i click save button this is not saved to the Database(Sahrepoint 2013 online list)

The starange thing is if i add more item by click the "Add" button then it works.

ANy help is appreciated

Answer 1

It is probably due to SharePoint not recognizing that you have changed anything in the GUI, hence there is nothing to save according to SP.

Try calling for example yourControl.change() from your script and see if SharePoint recognizes that as a change.
