Sometimes shows content and sometimes not on setdata()

Having a small issue where sometimes the editor will show the contents from setdata and sometimes not. I can refresh the page and have content load and then refresh and have it be blank?

Details: I set up the editor and call a function that does a setdata

$(function () {
  		CKEDITOR.config.toolbar = [
   			['Styles','Format','Font','FontSize'],
			['Bold','Italic','Underline','StrikeThrough','-','Undo','Redo','-','Cut','Copy','Paste','Find','Replace','-','Outdent','Indent','-','Print'],
			['NumberedList','BulletedList','-','JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'],
			['TextColor','BGColor']
		] ;
		
  		CKEDITOR.replace('Comments');
  		
  		fillit();
  		
  	});

before the fillit() function was also on page load but I though I was having issues with async doing both at once (aka trying to setdata to something that was not there yet). The fillit() function makes a JSON call and gets data to put in the editor.

portion of my success function from the $.ajax

success: function (data) {
	  			
	  			//parse the JSON
	  			var tmp = $.parseJSON(data);
	  			
	  			//alert(tmp[0].Name);
	  			
	  			//populate boxes
			  	$("#phone").val(tmp[0].Phone);
			  	$("#name").val(tmp[0].Name);
			  	$("#pext").val(tmp[0].PExt);
			  	$("#address").val(tmp[0].Address);
			  	$("#city").val(tmp[0].City);
			  	$("#prov").val(tmp[0].Prov);
			  	$("#pcode").val(tmp[0].PCode);
			  	$("#HOO").val(tmp[0].HOO);
			  	$("#contact").val(tmp[0].Contact);
			  	$("#billedto").val(tmp[0].BilledTo);
			  	$("#territory").val(tmp[0].Territory);
			  	$("#ClientCustNum").val(tmp[0].ClientCustNum);
			  	$("#PONum").val(tmp[0].PONum)
	  			$("#CustID").val(tmp[0].CustID);
	  			$("#CallType").val(tmp[0].CallType);
				CKEDITOR.instances.Comments.setData(tmp[0].Comments);

This does work but sometimes when the pages loads the editor will be blank and other times (refreshing that page) it loads the content. I can sit here pressing F5 and it will load fine on some refreshes and not on others.

Any ideas?

Thank you for any help,
