[TinyMCE] Extended_valid_elements for editor role

I’m using the following function to allow input elements in TinyMCE, but it doesnt work with the editor role.

When i log in as an administrator the function works fine and the input-element is kept in the source code. When i log in as editor the element is removed from the source code.

How can i make the input tag valid for editor users ?

function my_valid_elements($initArray) {
    $elements = array(
      'input' => 'input[id|name|class|style|value|type|checked|disabled|tabindex|accesskey|maxlength]'
    ); 

    $ext = implode(',', $elements);
    if ( isset( $initArray['extended_valid_elements'] ) ) {
        $initArray['extended_valid_elements'] .= ',' . $ext;
    } else {
        $initArray['extended_valid_elements'] = $ext;
    }
    return $initArray;
}
add_filter('tiny_mce_before_init', 'my_valid_elements');
