How can I get config values from js controller?

We are running Sugar 7.2.1 Pro and I can't figure out how to retrieve the values defined in the viewdefs config array. I just simply want to lookup the values of an enum field defined there using javascript.

Here is the config array within my viewdefs:
'config' => array(
    'fields' => array(
        'feed_urls' => array(
            'label' => 'Feed(s)',
             'name' => 'feed_urls',
             'type' => 'enum',
             'isMultiSelect' => true,
             'options' => array(
                 'key1' => 'value1',
                 'key2' => 'value2'
             )
         )
     ) 
)
I've tried using the 'this.model.get' function, but the documentation is not clear on what to pass to it. I tried:
this.model.get("config")
this.model.get("fields")
this.model.get("feed_urls")
All of which returned undefined.

How can I get to that options array?
