+ * {@link TBaseActiveCallbackControl::getJavascript ActiveControl.Javascript} property.
+ * The event {@link onCallback OnCallback} is raised when a callback is requested made.
+ *
+ * Example usage:
+ * <code>
+ * 	<com:TCallback ID="callback1" OnCallback="callback1_Requested" />
+ *  <script type="text/javascript">
+ * 		function do_callback1()
+ *      {
