Using the "scope" attribute to fetch values from views - Directive

Trying to create a dynamic button that changes styles on each click is proving challenging.

The console error "'initial' is not defined" has been persistent, despite my efforts to troubleshoot the issue.

Could it be an incorrect approach to retrieve a value from the view?

In addition, the click event I implemented in the link function doesn't seem to be functioning at all.

Your guidance on creating an effective angular directive would be greatly appreciated! Thank you!

                     }
                  }); 
               }
            };
         });
     });

primary is within the scope, hence it must be retrieved using scope.primary (similarly for core and later). As a result, it cannot be accessed in the compile() function and any code there must be transferred to the link() function.
