I was able to get an answer from the Polymer slack community. My issue is
that the code I was referencing was using Polymer 2x, whereas I'm using
Polymer 1.6.1. In 1.x, creating a binding using foo="[[bar]]" automatically
assumes that bar is a property of the current element, whereas in 2x, bar
could either be a property or a function. In 1x, to do what I need to do, I
have to define a property that returns similar:
foo: {
type: Function,
value: function() {
return function(value) {
// do something with value here and return it
}
}
}
