why don’t use code

// creates the plugin
        tinymce.create('tinymce.plugins.ig_pb', {
            init : function(editor, controlManager) {

				editor.addButton('ig_pb_button', {
					title : Ig_Translate.inno_shortcode, // title of the button
					image : Ig_Translate.inno_icon,  // path to the button's image
					onclick: function() {
						// triggers the thickbox
						tb_show( Ig_Translate.inno_shortcode, '#TB_inline?width=' + 100 + '&height=' + 100 + '&inlineId=ig_pb-form' );
						// custom style
						$('#TB_window').css({'overflow-y' : 'auto', 'overflow-x' : 'hidden', 'height' : parseInt(jQuery(window).height()*0.9 - 3) + 'px'});
						$('#TB_ajaxContent').css({'width' : '95%', 'height' : '90%'});
					}
				});

            }
        });

        // registers the plugin. DON'T MISS THIS STEP!!!
        tinymce.PluginManager.add('ig_pb', tinymce.plugins.ig_pb);

function filter_mce_plugin( $plugins ) {
		if ( floatval(get_bloginfo('version')) >= 3.9){
			$plugins['ig_pb'] = IG_Pb_Helper_Functions::path( 'assets/innogears' ) . '/js/tinymce_latest.js';
		} else {
			$plugins['ig_pb'] = IG_Pb_Helper_Functions::path( 'assets/innogears' ) . '/js/tinymce.js';
		}
		return $plugins;
	}

I think really nice if use button from tinymce.
