Can't use handlebars variable twice in each loop

I'm quite new to ember.js and handlebars and I'm trying to iterate through an array in my template.

<select name="district" id="select-district">
   {{#each districts}}
   <option value={{name}}> {{name}} ({{count}})</option>
   {{/each}}
</select>

Is there anything I am missing? Everything works fine when I remove the second variable name inside the loop. It seems like there is a problem in using a variable twice inside the loop.

The error: Uncaught TypeError: Cannot read property 'insertBefore' of null Any help would be greatly appreciated!
