I searched the whole internet and no solution works. I have the following helper:

 Handlebars.registerHelper('ifeq', function (a, b, options) {
        if (a == b) { return options.fn(this); }
        return options.inverse(this);
    });

I want to use helper in my .hbs file:

 {{#ifeq variable "string"}} 
        ... do this ... 
    {{/ifeq}}

Where do I insert first piece of code, if I want to use that helper in my .hbs file? I've tried various ways, but every time I get the error: "Missing helper: ifeq".
