* Match methods on `obj` of the form "_onCssClassAction", extracting
* "CssClass" and "Action", then:
*
* - Transform "CssClass" to ".cssClass"
* - Transform "Action" to "action"
* - Find elements matching .cssClass inside `elem`
* - Wire up the corresponding jQuery action (e.g. click()) to a bound
* copy of the method.

You can’t perform that action at this time.
