I have a grid setup to show a popup editor for creating items. The problem I am running into is that depending on what the user selects in the popup editor, the code might create more than one item. The controller method is returning all of the created items but only the first one gets added to the grid. How do I either a) get the grid to show all of my added items or b) refresh the grid? I can't just reload the page because there are other items on that page that I don't want to reload.
