Expand the same cell and force its reload?

[gerchicov-bp]

I have a cell with 2 buttons. Each button may expand cell. The expanded cell is the same but can have different data. For example in my case it contains DatePicker and a button but DatePicker's value depends on which cell button is pressed.
If I do it as described in your template then I call expandCell multiple times but it seems all the calls are ignored except of the first one.
Calling unexpandCell before each expandCell is not a solution too - the cell is collapsed and expanded again with animation.
