Function inside a button? Function inside a collision?

Hello,

I have some code (a function) that i want to add in a button/collision. But can't seem to make it work, does any one know how? I want to press a button, then the function is activated and working. Same thing with the collision.

Thanks a lot for your help!

Code that i want to add in a collision and a button:

--The function i want to add:
 
local function clearLines(event)
        for i = 1, #rectangle_hit, 1 do
              rectangle_hit[i]:removeSelf()
              rectangle_hit[i] = nil
        end
end
 
 
Button Code:
 
local button2Press = function( event )
 
-- Adding the function in the button didn't seem to work? 
 
end
 
local drop1 = ui.newButton{
        default = "drop.png",
        over = "drop.png",
        onPress = button2Press,
        emboss = true
}
 
drop1.x = display.contentWidth/14
drop1.y = display.contentHeight/1.1
drop1.rotation = -90
 
 
-- Collision code:
 
ball.myName = "ball"
snow.myName = "snow"
 
ball:addEventListener("collision", ball)
 
function ball:collision (event)
        if event.other.myName == "snow" then
 
-- I want to add the function in the collision ...? 
 
        end
end

for a button its basic stuff:

local function button2Press(event)
        if event.phase == "ended" then
                clearLines()
end
end
 
button2:addEventListener("touch", button2Press)
