Translations With Bound Parameters Display [object Object]

[heathharrelson]

When bound parameters are passed into the t Handlebars helper, the output is [object Object]. For instance, in a test like the following where testarg is __count__ frogs in the 'en' locale and model.count is 1000

{{t "testarg" count=model.count}}

the browser displays [object Object] instead of the expected '1000 frogs'.

The browser may be displaying the result of calling toString on the stream returned from the helper, rather than the stream's value. Debugging code shows that the stream's value function is never called.

Changing the helper to unbound allows it to display '1000 frogs', but as expected the count does not update when the model is changed.
