[QML] Trouble accessing MS elements and properties

I don't seem to be able to access anything different than a chord (and notes).
Can someone post an example that goes through a score to access e.g. a dynamic marking?

{syntaxhighlighter brush:cpp}
if(cursor.element.type == Element.CHORD) //does work
//EVERYTHING ELSE, like:
if(cursor.element.type == Element.DYNAMIC)
//do not work

[...]

while (segment) {
var element = segment.elementAt(track);
if (element) {
var typeName = element.userName();
console.log(typeName);
/* this last instruction only gives these types of elements:
"Clef, Key Armature, Chord, Rest", and maybe something else;
but no .TEXT, for example. No .DYNAMIC., .SLUR., .SLUR_SEGMENT, etc.,
even though I have these elements in my score.
