Locally tested with a {N} 3.0 non-Angular starter app with this added to the XML:

        <TextField text="blurrable textfield" blur="{{ onBlur }}"/>
        <TextField text="non-blurrable textfield"/>

And this added to main-view-model.js:

    viewModel.onBlur = function() {
        console.log("Blurred!");
        this.set("message", "Blurred @ " + new Date().getTime());
    }
