Associate multiple disks in azure vm using terraform

I am trying to create multiple vms and managed disk to associate after creation. I could see the disks are created and getting associated only for the first VM in the list. I am not sure how to assign the right index number in the below code.

I believe Virtual_Machine_id is creating this issue, has any one came across the similar, please advice.

'''resource “azurerm_managed_disk” “app_managed_disk” {

  count = “${length(var.data_disk_names)}”

  name = “ var.apphostname−{var.data_disk_names[count.index %length(var.data_disk_names)]}”

  location = azurerm_resource_group.poc_rg.location

  resource_group_name = azurerm_resource_group.poc_rg.name

  storage_account_type = var.app_disk_type

  create_option = “Empty”

  disk_size_gb = “${var.data_disk_sizes[count.index % length(var.data_disk_sizes)]}”

}

resource “azurerm_virtual_machine_data_disk_attachment” “app_disk_attach” {

  count = “${length(var.data_disk_names)}”

  vm_count = length(var.vm_app_name)

  managed_disk_id = “${azurerm_managed_disk.app_managed_disk[count.index % length(azurerm_managed_disk.app_managed_disk)].id}”

  virtual_machine_id = azurerm_linux_virtual_machine.app-vm-pas[0].id

  lun = “${count.index + 1}”

  caching = “ReadWrite”

}
