I have an issue on widget events. I have created a figure which contains several subplots. When click on one of the subplots, it shows another figure. This new figure contains button and rectangle selector widgets. Until this it works fine. Problem is nothing happens if I click on the buttons or draw rectangle on this new figure. It works well (i mean button onclick, line_select_callback events raise ), if I just create figure not after click the subplots. I do not know what I am doing wrong. Please help me.

By the way, I am using:
matplotlib.version : '1.4.3'
matplotlib.get_backend() : Qt4Agg
python: 2.7.10 | Anaconda 2.3.0 (64-bit)
