Use Meteor Iron Router data context in regular JS file?

Iron Router Code:

this.route('petProfile', {
    path: '/pets/:_id',
    data: function(){
        return Adoptees.findOne(this.params._id);
    }
});

      

        
        
        
      

    

It's pretty straightforward. If I have a key petName

for every object in the collection Adoptees

, I can simply use handlebars templates to access the data context.

petProfile.html:

<template name="petProfile">
    <h1>{{petName}}</h1>
</template>

      

        
        
        
      

    

But say that I want to have a data context in a linked javascript file:

petProfile.js:

Template.petProfile.rendered = function() {
    var petName = //How do I get the pet name from the data context in Iron Router?
}

      

        
        
        
      

    

Great, it works. So based on saimeunt's answer, I can simply do:

petProfile.js:

Template.petProfile.rendered = function() {
    var petName = this.data.petName;
}
