Sorry, I should have been more explicit.
The UnprefixedAttribute is your "onclick" attribute. The first parameter
(a string) is "onclick." The third parambers (MetaData) is null. What
you are passing is the second parameter, which can be a) an Option
containing a Seq of scala.xml.Nodes, b) another String, or c) a Seq of
scala.xml.Nodes.
The ajaxCall method you are providing as the middle parameter to
UnprefixedAttribute returns (String, JsExp). This is a tuple, not an
Option, a String, or a Seq of Nodes. Therefore, you are setting this up
incorrectly.
So you need to look at ajaxCall and see how it is properly used.
