how to get array value in lua in not using id - lua

Question

i have this array in my lua...
local data = {}
data[1] = {}
data[1].title = "Crazy Song"
data[1].subtitle = "by Bruno Earth"
data[1].image = "note.png"
data[2] = {}
data[2].title = "Enter Sunman"
data[2].subtitle = "by Mentalica"
data[2].image = "note.png"
data[3] = {}
data[3].title = "Bitter Child of Mine"
data[3].subtitle = "by Gunz n bullets"
data[3].image = "note.png"
data[4] = {}
data[4].title = "Missed A thing"
data[4].subtitle = "by Ero-Smith"
data[4].image = "note.png"
data[5] = {}
data[5].title = "Pornstar"
data[5].subtitle = "by Nicklefront"
data[5].image = "note.png"
data[6] = {}
data[6].title = "Burner"
data[6].subtitle = "by Asher"
data[6].image = "note.png"
how can i get the array values by not using id on it. i just want to get the title for my conditional statement?
i try this in my code:
local getTitle = function(event)
print (".................")
print (event.target.id)
print (event.target.title)
end
but i got only this...
touch: began
touch: ended
.................
2
nil
how can i get and print the title of my array?
this is my code:
module(..., package.seeall)
display.setStatusBar( display.HiddenStatusBar )
function new()
local localGroup = display.newGroup()
local tableView = require("tableView")
local ui = require("ui")
--------------------------------------------------------------------------
local screenOffsetW, screenOffsetH = display.contentWidth - display.viewableContentWidth, display.contentHeight - display.viewableContentHeight
local songList
local backBtn
local detailScreenText
local background = display.newRect(0, 0, display.contentWidth, display.contentHeight)
background:setFillColor(0, 0, 0)
localGroup:insert(background)
local data = {}
--iPad: setup a color fill for selected items
local selected = display.newRect(0, 0, 50, 50) --add acolor fill to show the selected item
selected:setFillColor(67,141,241,180) --set the color fill to light blue
selected.isVisible = false --hide color fill until neede

function changeScene(e)
if e.phase == 'ended' then

print ("back!")
end
end

backBtn.x = math.floor(backBtn.width/2) + backBtn.width + screenOffsetW
backBtn.y = navBar.y
backBtn.scene = "menu"
backBtn:addEventListener("touch", changeScene)
return localGroup
end
