wp_editor not working in external file

I am pulling info from my WordPress database into a dropdown. When an option is selected from the dropdown, a div is populated with a form from another page. The page gets the info from the database based on the dropdown fine. The problem I am having is that wp_editor isn’t completely loading. The toolbar is missing, and clicking visual or text does nothing. Any help is appreciated.

Here is my code:

    	function event_editevent_page() {
		global $wpdb;
		?>
		<script>
			function showeditevent(str) {
				var location1 = window.location.href;
				var directoryPath = '<?php echo plugins_url(); ?>';
				//alert(directoryPath);
			    if (str == "") {
			        document.getElementById("txtEditevent").innerHTML = "";
			        return;
			    } else {
			        if (window.XMLHttpRequest) {
			            // code for IE7+, Firefox, Chrome, Opera, Safari
			            xmlhttp = new XMLHttpRequest();
			        } else {
			            // code for IE6, IE5
			            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
			        }
			        xmlhttp.onreadystatechange = function() {
			            if (this.readyState == 4 && this.status == 200) {
			                document.getElementById("txtEditevent").innerHTML = this.responseText;
			            }
			        };
			        xmlhttp.open("GET",directoryPath+"/events/editevent.php?q="+str,true);
			        xmlhttp.send();
			    }
			}
		</script>
		<?php
		
		echo "<h2>Edit Event</h2>";
		
		
		$sql = $wpdb->get_results("SELECT * FROM " . $wpdb->prefix . "cmc_events order by date, time");
		
		?>
		<form>
			<select name="editevent" id="editevent" onchange="showeditevent(this.value)">
				<option value="">Select Event</option>
				<?php
					foreach ($sql as $event) {
						$id = $event->id;
						$title = $event->title;
						$date = $event->date;
						$time = $event->time;
						?><option value="<?php echo $id; ?>"><?php echo $title . " - " . $date . " - " . $time; ?></option><?php
					}
				?>
			</select>
		</form>
		<div id="txtEditevent"></div>
		<?php
		
	}

	$info = $sql->info;

	$newdate = DateTime::createFromFormat('m-d-Y', $date)->format('Y-m-d');
    ?>
