Jquery Sortable and Dragable - Replace dragged content with Ajax result - jquery-ui

Question

This is probably a simple question, but how can I replace the thing I am dragging with html from an ajax call?
So, if the draggable items are just 'text' items (as below in the html snippet), and when I drag the thing I use a 'image' via the helper method, how can I 'on drop' not use either of them but insert the html as returned from a ajax call.
Where do I make the call (btw, using the 'input-type' value to the ajax call to get the correct html)?
How to I prevent the default 'dragged item' from being inserted? I.e. I don't want the div put in or the helper method image....
Do I need to add like a droppable or do I do this in the sortable on like the received event (kind of works, can't remove image but from help method)??? (I have been trying both, and whilst the ajax call worked and I get the data etc, given that I don't know how to prevent the default stuff being dropped I am not sure 'what' I am replacing with the 'result' from the call...)
$("#desktoplayout").sortable({
receive: function (event, ui) {
$(this).append('<div>html from ajax call</div>'); // kind of works... but the image from the 'helper method' on the 'draggable' is still there.
}
}); // A sortable list of stuff into which things are dragged.
var input-type;
$("#draggableItems .item").draggable({
connectToSortable: "#desktoplayout",
helper: function (event) {
return "<div class='item'><img src='/Images/Header.png' /></div>";
},
start: function (event, ui) {
input-type = $(this).find('.preview').data("input-type");
},
drag: function(e, t) {
},
stop: function(e, t) {
}
});
and
<div id="draggableItems">
<div class="item">
<div class="preview" data-input-type="1">
TEXT
</div>
</div>
</div>
Update
This seems to do what I wanted... is calling remove on the helper the correct way of doing this?
receive: function(event, ui) {
ui.helper.remove();
var $this = $(this);
$.get("somewhere", function(data) {
// Note: presume more logic here.....
$($this).append(data);
});
}

Here is a working example of one solution:
https://jsfiddle.net/Twisty/zh9szubf/
HTML
<div id="draggableItems">
<div class="item">
<div class="preview" data-input-type="1">
TEXT
</div>
</div>
</div>
<ul id="desktoplayout">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
JQuery
$(function() {
$("#desktoplayout").sortable({
receive: function(event, ui) {
var newItem;
$.post("/echo/html/", {
html: "<li class='newItem'>From Ajax</li>"
}, function(data) {
ui.helper.replaceWith(data);
});
}
});
var inputType;
$("#draggableItems .item").draggable({
connectToSortable: "#desktoplayout",
helper: function (event) {
return "<div class='item'><img src='/Images/Header.png' /></div>";
},
start: function(event, ui) {
inputType = ui.helper.find('.preview').data("input-type");
}
});
});
This will work with $.get() too, but for the example, it had to be $.post(). Basically, whatever you want top be the result, That code should be in the ui.helper.replaceWith() section.
