CKEdtor 4 and Plugin

Hello, I created a plugin to work in CKEditor Inline, however, I am not able to get when the person click and place the HTML tag, it continues changed in inline edit mode and I can not leave the option checked to undo the change as in such bold action. 

Does anyone know how to solve? Following code:

CKEDITOR.plugins.add( 'bbp', {
		    init: function( editor ) {
		        editor.ui.addButton( 'BB', {
		            label: 'Insert BB',
		            command: 'addBB',
		            toolbar: 'basicstyles'
		        });

		        editor.addCommand('addBB', {
		            exec: function (editor) {
		                editor.applyStyle(new CKEDITOR.style({
		                    Element : 'span',
		                    attributes : { class:'highlight-tagline active' }
		                }));
		            }
		        });

		    }
		});
