Simple TextBuffer Insert

I have a simple piece of code that uses ITextBuffer interface to insert some text.  Basically, I have to delete the line and then add some new text. I am not sure if this is the best way to do it but I have had some success in getting the code into the correct location using the following:

            var buffer = (ITextBuffer) sender;
            var startOfLine = curerntLine.Start.Position;
            buffer.Delete(new Span(curerntLine.Start, curerntLine.Length));
            // Insert code into the current line. 
            var edit = buffer.CreateEdit();
            edit.Insert(startOfLine, text);
            edit.Apply(); // Finished.

One of the problems is that when the code it inserted the cursor automatically ends up at the end of the document. The next. This is a problem for me. I need the cursor to be at the end of the inserted text so that more user input can be added directly after. 

I would still like to use the ITextBuffer interface instead of TextDocument.
