[1.7.10 UNLSOLVED] Biped Mob addRandomArmor() doesn't seem to work

I have a mob,that renders as a bided,his model extends the biped class and still somehow doesn't holds the item i tell him to do.

Here are my classes:

public class ModelDefaultOrcGuard extends ModelBiped

{

  //fields

public ModelRenderer bipedHead;

    public ModelRenderer bipedHeadwear;

    public ModelRenderer bipedBody;

    public ModelRenderer bipedRightArm;

    public ModelRenderer bipedLeftArm;

    public ModelRenderer bipedRightLeg;

    public ModelRenderer bipedLeftLeg;

  public ModelDefaultOrcGuard()

  {

    textureWidth = 64;

    textureHeight = 32;

      bipedHead = new ModelRenderer(this, 0, 0);

      bipedHead.addBox(-4F, -8F, -4F, 8, 8, ;

      bipedHead.setRotationPoint(0F, 0F, 0F);

      bipedHead.setTextureSize(64, 32);

      bipedHead.mirror = true;

      setRotation(bipedHead, 0F, 0F, 0F);

      bipedBody = new ModelRenderer(this, 16, 16);

      bipedBody.addBox(-4F, 0F, -2F, 8, 12, 4);

      bipedBody.setRotationPoint(0F, 0F, 0F);

      bipedBody.setTextureSize(64, 32);

      bipedBody.mirror = true;

      setRotation(bipedBody, 0F, 0F, 0F);

      bipedRightArm = new ModelRenderer(this, 40, 16);

      bipedRightArm.addBox(-3F, -2F, -2F, 4, 12, 4);

      bipedRightArm.setRotationPoint(-5F, 2F, 0F);

      bipedRightArm.setTextureSize(64, 32);
