failed to execute on node

Hi, I am creating my first control, but it gave me the below error, I attached the code in the init event, please advise.

public init(context: ComponentFramework.Context<IInputs>, notifyOutputChanged: () => void, state: ComponentFramework.Dictionary, container:HTMLDivElement)
	{
		this.localNotifyOutputChanged = notifyOutputChanged;

		//Configure buttons
		this.nextButtonElement = document.createElement("a");
		this.nextButtonElement.setAttribute("class","next");
		this.nextButtonElement.addEventListener("click",this.nextOnClick.bind(this));

	 	this.nextButtonElement = document.createElement("a");
		this.nextButtonElement.setAttribute("class","previous");
		this.nextButtonElement.addEventListener("click",this.previousOnClick.bind(this));

		this.spaceElement = document.createElement("span"); 

		var _previous = container.appendChild(this.previousButtonElement);
		var _space = container.appendChild(this.spaceElement);
		var _next = container.appendChild(this.nextButtonElement);
		_previous.innerHTML = "&laquo; Previous";
		_space.innerHTML = "&nbsp;";
		_next.innerHTML = "Next &raquo";
}
