Class Instance Issue

How can I get the instance of the class to call the dispatchEvent for the postTrace function.

1180: Call to a possibly undefined method dispatchEvent.


package {
	
	import flash.display.*;
	import flash.events.*;
	import flash.net.*;
	import flash.utils.*;

	
	public class Output {
		
		public var dataRequest:String;
		
		private static var requestPath:String;
		private var contentXML:XML;
		private var contentXMLURL:URLRequest;
		private var contentXMLLoader:URLLoader;
		
		public function Output(path) {
			requestPath = path;
		}
		
		public function getPost(postID) {
			trace("-----------------------\rpost: "+postID);
			var output:XMLList = xmlRequest('getPost', 'postID', postID);
			makeRequest();
		}
		public function getCategoryPosts(categoryID) {
			var output:XMLList = xmlRequest('getCategoryPosts', 'categoryID', categoryID);
		}
		public function getOutput() {
			return contentXML;
		}
		
		private function xmlRequest(method, type, val) {
			//data
			dataRequest = '<message library="pressConnect"><call callFunction="'+method+'" '+type+'="'+val+'"/></message>';
			trace("\rdataRequest:\r----------------------\r"+dataRequest);
		}
		private function makeRequest() {
			contentXMLURL = new URLRequest(requestPath);
			contentXMLURL.data = dataRequest;
			contentXMLURL.contentType = "text/xml";
			contentXMLURL.method = URLRequestMethod.POST;
			contentXMLLoader = new URLLoader(contentXMLURL);
			contentXMLLoader.addEventListener(Event.COMPLETE, loadComplete);
		}
		private function loadComplete(e:Event) {
			contentXML = new XML(contentXMLLoader.data);

			//THIS LINE ERRORS
			dispatchEvent(new Event(Event.COMPLETE));
			//
		}
		
	}
	
}



var post:Output = new Output('http://beta.130public.net/wp-request');
post.getPost('231');
post.addEventListener(Event.COMPLETE, postTrace);
function postTrace(e:Event) {
	trace(post.getOutput());
}
