javascript - How can I hook a double click event from an ExtJs RowBody? -

I'm using an Ext.grid.plugin.RowExpander which is the extension for Ext.grid as the base. Uses feature.RowBody In the grid there is a double click listener who opens a window. The problem is that double clicking on the robody does not come with a double click event on the grid and I can not even get a way to hook the event.

I was dumb and did not read the documentation for Ext.grid.feature.RowBody. It clearly states that this feature displays "Extra" events on Gridview, including Rowboodideblocal. There is some difficulty in knowing which row or more important in the grid that the robody who triggers the event records.
