Connect Video Player with alloy

hello I do not know how to add video from JS to XML

.js

var args = arguments[0] || {}; var miId2 = args.miId; // alert("idrow:" + miId2); var argsDetalle = {}; var pista;

function atras() { $.vistaDetalle.close(); }

var momiasC = Alloy.Collections.momiasCollection;

var lg = Ti.Locale.currentLanguage.indexOf("es"); //length

momiasC.fetch({ query : "SELECT * FROM momias WHERE qrcode='" + miId2 + "'" }); Ti.API.info("length" + momiasC.length); var nol = momiasC.length; if (nol > 0) { momiasC.forEach(function(e) { Ti.API.info("LG" + Ti.Platform.locale); Ti.API.info("celda" + JSON.stringify(e)); Ti.API.info("loqueda " + lg);

    $.title.text = e.get("nombre");
    $.imagen.image = "/imagesMomias/" + e.get("foto");

    if (lg >= 0) {
        $.descripcion.text = e.get("despicion");
        setPlayer("/audios/" + e.get("idaudioespañol") + ".mp4");
    } else {
        $.descripcion.text = e.get("ingles");
        setPlayer("/audios/" + e.get("idaudioingles") + ".mp4");

    }
});
$.vistaDetalle.open({
    transition : Titanium.UI.iPhone.AnimationStyle.NONE
});

} else {

alert("no existe");

}

function setPlayer(pista) {

var videoPlayer = Titanium.Media.createVideoPlayer({

    url : pista,
    // title : descripcion,
    autoplay : true,
    // backgroundColor : 'black',
    height : 300,
    width : 300,
    // fullscreen : true,

    mediaControlStyle : Titanium.Media.VIDEO_CONTROL_DEFAULT,

    // scalingMode : Titanium.Media.VIDEO_SCALING_ASPECT_FIT

});

}
