Meteor Handlebars: What is the proper way in a condition to compare two variables?

I can't figure out a way to do something like this in a Template with Meteor and Handlebars:

{{#if var1 == var2}}
{{/if}}

I've also set up the Meteor Handlebars Helpers and this seems not to work too while it should:

{{#if $eq var1 var2}}
{{/if}}

So what is your proper way to compare two variables with Handlebars in a Template?

EDIT: In fact, this seems to go beyond the Handlebar ideology which is that there should be no logic in templates.

For now this is not as easy as you might aspect. I thought i have read that this is maybe a feature in meteor 1.0.

You have the 3 following possibilities:

html:

<template name="stuff">
  {{#if isTrue}}
    ...
  {{else}}
    ...
  {{/if}}
</template>

js:

Template.stuff.helpers({
  isTrue: function () {
    return var1 === var2;
  }
});

Another possibility is to provide an own handlebars helper:

html:

{{compare "var1" "var2"}}

js:

Handlebars.registerHelper('compare', function(var1, var2) {
  return var1 === var2;
});

Or you use any other Handlebars-helper package where someone already did the work for you. I dont know the package you used, so i cant give a detailed solution about your problem but maybe you get a nice view of how this can be realised.
