What's the language equivalent of do nothing next?

I have my component:

record Node.Rec {
	id : String,
	x : Number,
	y : Number
}

enum Node.Action {
	None
	Clicked
}

component Node {
	property node : Node.Rec
	property radius : Number

	state action = Node.Action::None

	fun moveNode(element : Dom.Element, x : Number, y : Number) {
		element
		|> Dom.setAttribute("x", Number.toString(x))
		|> Dom.setAttribute("y", Number.toString(y))
	}

	fun onDrag(event : Html.Event) {
		if (action == Node.Action::Clicked) {
			case (circle) {
				Maybe::Just(el) => moveNode(el, event.clientX, event.clientY)
				=> next {}
			}
		} else {
			next {}
		}
	}
	/*
	fun onDragEnd(event) {

	}
	*/

	fun render : Html {
		<circle as circle
			onMouseDown={() {
				next { action = Node.Action::Clicked }
			}}
			onMouseMove={onDrag}
			cx={Number.toString(node.x)}
			cy={Number.toString(node.y)}
			fill="red"
			r={Number.toString(radius)}
		/>
	}
}

onDrag should modify, the element position, however, I'm now getting type mismatch because next {} returns different type, than the Dom.element functions
