I have duplicated a symbol that contains text. How do I make the duplicated symbol unique, so when I edit the text the original symbol does not change?
Duplicate the symbol in the library, not the elements panel. This way you will have to similar looking symbols but they are still 2 unique symbols.
Otherwise if you duplicated in the elements panel you can just use this:
sym.getSymbol('yourDuplicatedSymbolNameHere').$('YourTextNameHere').html('Your new unique text here');
