Cambiare attributo SVG con jQuery

In sostanza sto usando un plugin che crea delle icone SVG on the fly.

Dopo aver fatto tutta una procedura, devo cambiare un attributo; nello specifico il fill.

Partiamo dall' SVG di base:

<svg width="54px" 
	height="54px" 
	viewBox="0 0 54 54" 
	version="1.1" 
	xmlns="http://www.w3.org/2000/svg"
	xmlns:xlink="http://www.w3.org/1999/xlink" 
	xmlns:sketch="http://www.bohemiancoding.com/sketch/ns">
		<title>Check</title>
		<defs></defs>
		<g id="Page-1" stroke="none" stroke-width="1" fill="#000000" fill-rule="evenodd" sketch:type="MSPage">
        <path d="M23.5,31.8431458 L17.5852419,25.9283877 C16.0248253,24.3679711 13.4910294,24.366835 11.9289322,25.9289322 C10.3700136,27.4878508 10.3665912,30.0234455 11.9283877,31.5852419 L20.4147581,40.0716123 C20.5133999,40.1702541 20.6159315,40.2626649 20.7218615,40.3488435 C22.2835669,41.8725651 24.794234,41.8626202 26.3461564,40.3106978 L43.3106978,23.3461564 C44.8771021,21.7797521 44.8758057,19.2483887 43.3137085,17.6862915 C41.7547899,16.1273729 39.2176035,16.1255422 37.6538436,17.6893022 L23.5,31.8431458 Z M27,53 C41.3594035,53 53,41.3594035 53,27 C53,12.6405965 41.3594035,1 27,1 C12.6405965,1 1,12.6405965 1,27 C1,41.3594035 12.6405965,53 27,53 Z"
			id="Oval-2" 
			stroke-opacity="0.198794158" 
			stroke="#747474" 
			fill-opacity="0.816519475" 
			fill="#FFFFFF"
			sketch:type="MSShapeGroup">
        </path>
    </g>
</svg>

Per cambiare l'attributo:

$('#Oval-2').attr("fill", "#5ab75a");

Enjoy!
