Not necessarily, all you need to do is listen for an afterCommandExec event. When that happens, check to see which command was pressed.

here is a sample code

CKEDITOR.plugins.add( 'adico',
{
   init : function( editor )
        {
           // afterCommandExec
            editor.on( 'afterCommandExec', function(event)
            {
             var commandName = event.data.name;
         
                       // For 'bold' commmand
                       if (commandName == 'bold')
                            alert("Bold button pressed!");
                  });
          }
      });

add this plugin to your config.js file:
config.extraPlugins = 'adico;

and that should be it.
