Pass variable from #each loop to helper emberjs

I'm having problems passing template variables into helpers, i got a template like that

{{#each row in workpage.mainStructure}} <div class='row'> <div class='cell cell-2'>{{i18nForecasts row.value }}</div> {{#each cell in row.amounts}} <div class='cell'>{{cell.format}}</div> {{/each}} </div> {{/each}}

and my helpers only needs to log the passing val:

 Ember.Handlebars.registerHelper('i18nForecasts', function(property, options) {   
   var escaped = Handlebars.Utils.escapeExpression(property);
  console.log(escaped);
});

The thing is that i only get the value as 'row' in string and not the looping values. but if i try to print the value with out the helper like:

{{row.value}}

It prints the correct loop value.

You'll want to use registerBoundHelper, http://emberjs.com/api/classes/Ember.Handlebars.html#method_registerBoundHelper

Ember.Handlebars.registerBoundHelper('i18nForecasts', function(property, options) {   
   var escaped = Handlebars.Utils.escapeExpression(property);
   console.log(escaped);
});
