create multiple buttons from table in lua ( Corona sdk ) - button

Question

I have a table which looks like this:
table =
{
{
id = 1,
name = 'john',
png = 'john.png',
descr = "..."
},
{
id = 2,
name = 'sam',
png = "sam.png",
descr = "..."
}
...
}
What function could I use to display each picture like this and make them buttons
so that when I click on their image I can open their info.
This is where I am stuck:
local buttons = display.newGroup()
local xpos = -20
local ypos = 0
local e = -1
function addpicture ()
for i=1, #table do
xpos = (xpos + 100) % 300
e = e + 1
ypos = math.modf((e)*1/3) * 100 + 100
local c = display.newImage( table[i].name, system.TemporaryDirectory, xpos, ypos)
c:scale( 0.4, 0.4 )
c.name = table[i].tvname
buttons:insert(c)
end
end
function buttons:touch( event )
if event.phase == "began" then
print(self, event.id)
end
end
buttons:addEventListener('touch', buttons)
addpicture()
How can I recognize which image is touched in order to go back to the persons info?

Answer 1

I solved my problem by adding the listener inside of the loop like this:
function addpicture ()
for i=1, #table do
xpos = (xpos + 100) % 300
e = e + 1
ypos = math.modf((e)*1/3) * 100 + 100
local c = display.newImage( table[i].name, system.TemporaryDirectory, xpos, ypos)
c:scale( 0.4, 0.4 )
c.name = table[i].tvname
buttons:insert(c)
function c:touch( event )
if event.phase == "began" then
print(self, event.id)
end
end
c:addEventListener('touch', c)
end
end
addpicture()
