You need to specify client IDs-to-render in the <f:ajax render> attribute.
Thus, given that the second textarea has an ID of headadd, this should do:
<f:ajax ... render="headadd" />
Unrelated to the concrete problem, comparing booleans against booleans in a boolean expression really doesn't make any sense. Just check the boolean itself directly.
if (current.getCheckBox())
By the way, try to use self-documenting property and method names. A property name of remember would be more suitable.
