method prepareBinding

dynamic prepareBinding(String path, name, node)

Prepares a binding. This is called immediately after parsing a mustache token with {{ path }} in the context of the node and the property named name. This should return a function that will be passed the actual node and model, and either returns null or an object with a value property. This allows the syntax to reinterpret the model for each binding.
