Insert into grid not adding datapoint


I am running a RoR website and I want to have a table of some datapoints. I have a database set up and can display my points. I am using dataprocessor. I can edit them fine. When I try to add a new point, it makes a new row but the cells stay bolded. I cannot prepopulate any of the data because I need it to be new. When making a new point, it adds the row but all of the parameters are empty. Is there anyway to wait until the data is entered before calling the “inserted” method from the dataprocessor?
