render method in my AbstractContainerScreen class

 

@Override
    protected void renderBg(PoseStack poseStack, float pPartialTick, int mouseX, int mouseY) {
        RenderSystem.setShader(GameRenderer::getPositionTexShader);
        RenderSystem.setShaderColor(1.0F, 1.0F, 1.0F, 1.0F);
        RenderSystem.setShaderTexture(0, TEXTURE);
        this.blit(poseStack,leftPos,topPos,0,0, imageWidth, imageHeight);

        ItemStack stack = new ItemStack(SItems.REDSTONE_SILICON,64);
        String count = String.valueOf(stack.getCount());
  		//render item model
        itemRenderer.renderGuiItem(stack,mouseX,mouseY);
  		//render my string (64 in iamge)
        font.draw(poseStack,count,mouseX+(-font.width(count)+20),mouseY+10,0xFFFFFF);

    }

@Override
    public void render(PoseStack poseStack, int mouseX, int mouseY, float delta) {
        renderBackground(poseStack);
        super.render(poseStack, mouseX, mouseY, delta);
        renderTooltip(poseStack, mouseX, mouseY);
    }

but the string is below the item:

I am not good at rendering, but it looks like you have depth test issues, probably caused by the blending used by the item render?

If you can't use ItemRenderer.renderGuiItemDecorations() for some reason, have it look at what it does.

You might also want to look at AbstractContainerScreen.renderSlot()

Taking a look at AbstractContainerScreen.renderSlot() I got the following code:

Method created in my AbstractContainerScreen class:

private void renderCustomSlot(PoseStack poseStack,ItemStack itemstack,int x, int y) {
        boolean visible = true;
        boolean hover = false;

        this.setBlitOffset(100);
        this.itemRenderer.blitOffset = 100.0F;

        if (visible) {
            if (hover) {
                //Draw a rectangle behind the item
                fill(poseStack, x, y, x + 16, y + 16, -2130706433);
            }

            //Render item icon
            RenderSystem.enableDepthTest();
            this.itemRenderer.renderAndDecorateItem(this.minecraft.player, itemstack, x, y, x + y * this.imageWidth);

            //Render item string count
            PoseStack posestack = new PoseStack();
            if (itemstack.getCount() != 1) {
                String s = String.valueOf(itemstack.getCount());
                posestack.translate(0.0D, 0.0D, itemRenderer.blitOffset + 200.0F);
                MultiBufferSource.BufferSource multibuffersource$buffersource = MultiBufferSource.immediate(Tesselator.getInstance().getBuilder());

                /*
                float scale;
                if (s.length()<3){
                    scale=1f;
                }else if (s.length()<4){
                    scale = 0.75f;
                }else {
                    scale=0.5f;
                    s = s.substring(0,s.length()-3)+"k";
                }

                float compensatingScale = 1/scale;

                float stringX = (x + 19f - 2 - font.width(s)*scale)*compensatingScale;
                float stringY =(y + 6f + 3)*compensatingScale;

                posestack.scale(scale,scale,scale);
				*/
				float stringX = (x + 19f - 2 - font.width(s));
                float stringY =(y + 6f + 3);
                font.drawInBatch(s,stringX,stringY,16777215, true, posestack.last().pose(), multibuffersource$buffersource, false, 0, 15728880);
                //posestack.scale(compensatingScale,compensatingScale,compensatingScale);

                multibuffersource$buffersource.endBatch();
            }
        }

        this.itemRenderer.blitOffset = 0.0F;
        this.setBlitOffset(0);
    }

Now it works correctly:
