Is it possible to use function in Handlebars #if?

Question

I have a controller object that\'s like:

MyApp.objController = Ember.ArrayController.create({
  init: function(data) {
    data.isValid = function() {
      retu

Try this:

  {{#each subsites}}
    {{#if this}}
      
{{{WhatIsTheSiteFor this}}}
    {{else}}
      
no found
    {{/if}}
  {{/each}}

The helper function WhatIsTheSiteFor:

Handlebars.registerHelper('WhatIsTheSiteFor', function(siteName) {
  var subSiteName = '',
      siteNameStr = '';

  $.each(siteName, function(i, item) {
    siteNameStr += item;
    return siteNameStr;
  });

  if(siteNameStr === 's.gbin1.com') {
    subSiteName = 'GB搜索引擎';
  }
  else if (siteNameStr === 'm.gbin1.com') {
    subSiteName = 'GB手机阅读';
  }
  else if (siteNameStr === 'rss.gbin1.com') {
    subSiteName = 'RSS消息订阅';
  }

  return subSiteName;
});
