Mouse wheel is not moving scroll bar

[Circuits]

Hey guys, I have built a custom scroll bar for this TableView like so:

  TableView
  {
    id: _sectionDetails
    
    anchors.margins: sectionReviewPage.style.padding
    width: parent.width
    height: 350
    selectionMode: SelectionMode.NoSelection
    backgroundVisible: false
    frameVisible: false
    verticalScrollBarPolicy: Qt.ScrollBarAlwaysOff

    Binding
    {
      target: _sectionDetails.flickableItem
      property: "contentY"
      value: (_sectionDetails.flickableItem.contentHeight) * vbar.position - (27 - vbar.position)
    }

    ScrollBar
    {
      id: vbar

      width: 20
      active: true
      size: (_sectionDetails.height) / (_sectionDetails.flickableItem.contentItem.height)
      orientation: Qt.Vertical
      anchors
      {
        top: _sectionDetails.top
        left: _sectionDetails.right
        bottom: _sectionDetails.bottom
      }
      contentItem: Rectangle
      {
        id: contentItem_rect2

        color: themeManager.currentTheme.palette.highlightColor
        width: 10 // This will be overridden by the width of the scrollbar
        height: 10 // This will be overridden based on the size of the scrollbar
        radius: 5
        opacity: 1
      }
    }

For some reason, using the mouse wheel is not making the scroll bar move. It still movies the TableView. I guess I would have thought that binding would be done by default but apparently not. What binding do I need here?

EDIT: Perhaps I am just approaching this wrong? The default scroll bar that the view provides works perfectly and is great in every aspect except the way it looks. I just want to change the way it looks s/t it is styled as above. I feel like I shouldn't have to remove it to make that happen but I couldn't figure out an easier way.

Problem solved using the style: TableViewStyle{}

    style: TableViewStyle
    {

      decrementControl: Rectangle
      {
        anchors.fill: parent
        visible: false
      }
      incrementControl: Rectangle
      {
        anchors.fill: parent
        visible: false
      }
      scrollBarBackground: Rectangle
      {
        implicitWidth: 20
        color: sectionReviewPage.style.backgroundColor
        radius: 5
        opacity: 1
      }
      handle: Rectangle
      {
        implicitWidth: 20
        color: themeManager.currentTheme.palette.highlightColor
        radius: 5
        opacity: 1
      }
    }
