How do I get the original value in handlebars register helpers?

I have moved into latest Ember version 1.9.1 and Handlebars version 2.0.0. In this, I am getting an error like "Usage of Ember.Handlebars.get is deprecated, use a Component or Ember.Handlebars.makeBoundHelper instead."

I have a code like this,

Handlebars.registerHelper('ifCond', function (temp_v1, operator, temp_v2, options) { // No I18N

    var v1,v2;
    v1 = Ember.Handlebars.get(this, temp_v1, options);
    v2 = Ember.Handlebars.get(this, temp_v2, options);

        if( v1 == undefined ){
            v1 = temp_v1;
        }
        if( v2 == undefined ){
            v2 = temp_v2;
        }


        switch (operator) {
          case '==':
            return (v1 == v2) ? options.fn(this) : options.inverse(this);
          case '!=':
            return (v1 != v2) ? options.fn(this) : options.inverse(this);
          default:
            return options.inverse(this);
        }
 });

Here, I need to check the given string value is equal or not. If I remove the "Handlebars" in Ember.Handlebars.get(this, temp_v1, options), that deprecation error will be gone. But I couldn't get the original value of temp_v1.
