TActiveTextBox allows the {@link setText Text} property of the textbox to
be changed during callback. When {@link setAutoPostBack AutoPostBack} property
is true, changes to the textbox contents will perform a callback request causing
{@link onTextChanged OnTextChanged} to be fired first followed by {@link onCallback OnCallback}
event.
