Deprecation in ember verision 1.9.1. getting deprecation warining Ember.Handlebars.get() is deprecated, use Ember.makeBoundHelper

I've just moved to ember 1.9.1. I have on custom helper named 'ifCond'. Am using registerHelper function to register the 'ifCond' helper. My registerHelper function looks like this.

Ember.Handlebars.registerHelper('ifCond', function (temp_v1, operator, temp_v2, options) {
    var v1 = temp_v1, v2 = temp_v2;
    v1 = Ember.HandleBars.get(this, temp_v1, options);
});

I tried writing makeBoundHelper function in /app/helper/if-cond.js. But did not work out. What's the proper way of registering new helper in ember 1.9.1?
