print function source code

[hanai]

I followed this tutorial https://www.meteor.com/tutorials/blaze/temporary-ui-state.

I tried

sync: {
    incompleteCount: function () {
      return Tasks.find({checked: {$ne: true}}).count();
    }
}

 <header>
      <h1>Todo List ({{incompleteCount}})</h1>
      <label class="hide-completed">

when incompleteCount equals 0, the page print out source code

oh, can you try [[ instead of {{? we change that to avoid the conflict of blaze
