I have problem accessing the data in the def function.
Just for an example, I have a data of

{"name":"Jake","age":31}

And here's a template file

{{##def.test = function(str) {
     return "My name is: " + str;
}
#}}
{{#def.test(name)}}

As I tested the result will print out "My name is:" instead of "My name is Jake".
Is there a way to passing data to def function?

something like this???:

{{#def.test("{{=it.name}}")}}

or

{{#def.test(it.name)}}
