Any content that is returned will be used to replace the content of the current element (or, more commonly, another
element, via the ic-target attribute, see below). An empty
response will be interpreted as a No-Op. See Intercooler Responses for
more info.
Since it is common for an action to replace a different element than the one that the action occured
on, you may want to use the ic-target attribute to target
a different element for replacement.
The default action depends on the type of an HTML element:
input, select - A value change.form - A form submission.
