Estou tentando configurar o Angular com o Laravel 5.

Eu tentei fazer no appServiceProvider:

public function boot()
{
    \Blade::setRawTags("[[", "]]");
    \Blade::setContentTags('<%', '%>'); // for variables and all things Blade
    \Blade::setEscapedContentTags('<%%', '%%>'); // for escaped data
}

Com:

<div>
  <input type="text" ng-model="yourName" placeholder="Enter a name here">
  <h1>Hello, {{ yourName }}!</h1>
</div>

Mas eu estou recebendo:

Use of undefined constant yourName - assumed 'yourName'...
