Using Custom Tags to Map HTML to Ti

html.js

function htmlToTi(_args){
	
	var json = {};
	var keys = _.keys(_args);
	
	_.each(keys, function(key){
		
		switch(key){
			case "bgcolor":
			case "background-color":
				json.backgroundColor = _args[key];
				break;
			case "height":
			case "width":
			case "top":
			case "left":
			case "bottom":
			case "right":
				json[key] = _args[key];
				break;
			case "style":
				//_.extend(json, htmlToTi()
				break;
			default:
		}
		
	});
	
	return json;
}


exports.creatediv = function(_args){
	
	var json = htmlToTi(_args);
	var view = Ti.UI.createView(json);
	
	return view;
	
};
exports.createDIV = exports.creatediv;
exports.createDiv = exports.creatediv;

<Alloy>
	<Window class="container">
		<div module="html" bgcolor="#f00" style="border-radius:3px" height="200" width="200">
			<div module="html" bgcolor="#00f" height="50" width="50" />
		</div>	
	</Window>
</Alloy>

I think you only need createDiv since Alloy will camelCase it for you.
