This isn't possible in Illustrator. A modal dialog, by definition, blocks the main thread of the app, and it is within this thread that all communication with Illustrator must occur. If it works for your use case, a floating dialog can be used instead, since it does not block the main thread (we do this in a plugin or two ourselves).
