Apply selection to layer mask

Question

Hello,
iam looking for a solution to apply a previeuws
selction to a layer mask of a adjustment layer.
My code mange to select the mask - but when i apply the
selection it creates layer above.
I need to go into the layer mask (alt and click) and then paste.
Then go out.
Scriptlistender isnt helping so much.
app.activeDocument.selection.selectAll(); //selects stuff on the preview layer
app.activeDocument.selection.copy();  //copy that stuff - to paste it into the mask later
var adjLayer = doc.layerSets.getByName("ao").artLayers.getByName("ao");  //searching for a group and specific layer
var mask = ExtendedLayer.selectLayerMask(adjLayer); // extern function wich selects the mask (does not go "into" the mask - just selects it)
pastMask = function()
// Selectin recorded by Script listender
var idslct = charIDToTypeID( "slct" );
    var desc321 = new ActionDescriptor();
    var idnull = charIDToTypeID( "null" );
        var ref212 = new ActionReference();
        var idChnl = charIDToTypeID( "Chnl" );
        var idChnl = charIDToTypeID( "Chnl" );
        var idMsk = charIDToTypeID( "Msk " );
        ref212.putEnumerated( idChnl, idChnl, idMsk );
    desc321.putReference( idnull, ref212 );
    var idMkVs = charIDToTypeID( "MkVs" );
    desc321.putBoolean( idMkVs, false );
executeAction( idslct, desc321, DialogModes.NO );
// paste, recorded by script listender
var idpast = charIDToTypeID( "past" );
    var desc322 = new ActionDescriptor();
    var idAntA = charIDToTypeID( "AntA" );
    var idAnnt = charIDToTypeID( "Annt" );
    var idAnno = charIDToTypeID( "Anno" );
    desc322.putEnumerated( idAntA, idAnnt, idAnno );
executeAction( idpast, desc322, DialogModes.NO );
pastMask();
Any help would be really nice.!
Thanks alot
