meteor - how to write if is not equal in blaze -

i have in js file:

  isadmin: function() {     if (meteor.user().roles[0] == "admin") {         return true;     } else {         return false;     } }, 

in html want if admin ==false.how it?

this true condition : want false

  {{#if isadmin}}        ...   {{/if}} 

is posible this?

  {{#if !isadmin}}        ...   {{/if}} 

i guess looking is

{{#unless isadmin}}     ... {{/unless}} 

have here @ docs.

btw, if using alanning:roles package, includes handy little helper blaze.

{{#unless isinrole 'admin'}}     ... {{/unless}} 

hope helps.
