The code Looks good to me but I have seen there are lost of Codacy errors https://app.codacy.com/manual/Akvo/akvo-flow/pullRequest?bid=15721359&prid=4706082&utm_campaign=new_commit&utm_medium=Email&utm_source=Internal&
My knowledge of Javascript does not allow me to tell if they are legit or not but @marvinkome I have invited you to that project in case you want to check them out.

@valllllll2000 they look more like repetitive formatting problems.

When searching for datapoints, I see that its only possible to search for the entire datapoint name and not partially. I recall the implementation was supposed to search for datapoints based on partially matching the display name, no? @stellanl actually implemented that in #3343

[marvinkome]

True. Forgot it was implemented. I'll update #3398 to match that. 👍🏼

So as a general comment, try to think of the datastructure that is relevant.. in this case the relevant one is the DataPointAssignment which contains the surveyAssignmentId, deviceId and the list of datapoints that are assigned to a particular device. The DataPointAssignment has a once to one correspondence with a device for each SurveyAssignment.

The code we are trying to write is operating on that datastructure. We enter a SurveyAssignmemt and in there when we select a device, we then start to manipulate a DataPointAssignment that is attached to that SurveyAssignmemnt.

With each datapoint that we select, the manipulation is to add or remove a datapointId top the list of ids in the DataPointAssignment. This basic idea should come through when reading the code. So in the code for instance, there should be a DataPointAssignment.
