Double click for Listview

I'm trying to adapt this:

GUIRegisterMsg($WM_LBUTTONDBLCLK, "_WM_LBUTTONDBLCLK")
Local $fDblClk = False
Local $iDoubleClickTime = 200 ; _WinAPI_GetDoubleClickTime() ; 500 by default

Func _WM_LBUTTONDBLCLK($hWnd, $iMsg, $iwParam, $ilParam)
    Local $iX = BitAND($ilParam, 0xFFFF), $iY = BitShift($ilParam, 16)

    $fDblClk = True
    ConsoleWrite("!Double click on: [" & $iX & "," & $iY & "]" & @CRLF)
    Return $GUI_RUNDEFMSG
EndFunc

To work on my List view. I already have a button called $Edit_Btn and I want to make it so when I doubleclick in the list view, it triggers the Edit_Btn case.

The code above seems to print out where I clicked on the console, but only when I click on the GUI background and not on the list view. Is there a easier way to make it so when I double click in a list view, it triggers the edit button?
