tkinter treeview click event for selected item [duplicate]

问题

In my small tkinter app I have tree with such scructure as in the picture below. I want to make click event only when user will double click to last item of the tree (Amount1 or Amount2 etc.) Unfortunatly click event works when I click any item of the tree. How fix this behavior?!

CODE:

self.treeView.insert('', 'end', "parent", text=text)

first_child = self.treeView.insert("parent", 'end', text=text)

second_child = self.treeView
second_child.insert(first_child, 'end', "", text=text)
second_child.bind("<Double-1>", self.OnDoubleClick)

def OnDoubleClick(self, event):
    item = second_child.identify('item', event.x, event.y)
    print("you clicked on", second_child.item(item, "text"))

Structure of the tree:

Certain state changes within a Treeview widget generate virtual events that you can use to respond to these changes; see Section 54.8, “Virtual events”.

Whenever there is a change in the selection, either by items becoming selected or becoming unselected, the widget generates a “<<TreeviewSelect>>” event.

Whenever an item is opened, the widget generates a “<<TreeviewOpen>>” event.

Whenever an item is closed, the widget generates a “<<TreeviewClose>>” event.
