TextEvents Not Working is Visual Studio Package

I have entered the following code into my visual studio package. Followed by setting a break point on the handler. The break point is never hit. My intentions are to read the current line and input and take action if it contains a particular string. 

    ...{    Events2 = Globals.Dte.Events as Events2;
            Events2.TextDocumentKeyPressEvents.AfterKeyPress += TextDocumentKeyPressEvents_AfterKeyPress;
            Events2.TextDocumentKeyPressEvents.BeforeKeyPress += TextDocumentKeyPressEvents_BeforeKeyPress;
        }

        void TextDocumentKeyPressEvents_BeforeKeyPress(string Keypress, TextSelection Selection, bool InStatementCompletion, ref bool CancelKeypress)
        {
            
        }

        void TextDocumentKeyPressEvents_AfterKeyPress(string Keypress, TextSelection Selection, bool InStatementCompletion)
        {

        }

Seems like a pretty straight forward code snippet. Any help would be greatly appreciated.
