No filter row shown at all

[Gargaroz]

Dear @tybeck,
I really like what you got here, but it looks like I can't make it work as expected.
I wrote the directive down inside the controller template like this:

<paasb-search-box
       search-params="searchctrl.sOptions"
      paasb-search-box-filtering="searchctrl.sFilters"
      paasb-search-box-enable-filtering-operators="true"
      paasb-search-box-config="searchctrl.sConfig"
      paasb-search-box-auto-complete="searchctrl.sConfig"
      paasb-search-box-cache-filter="true"
      paasb-search-box-filter-selectors="searchctrl.sFilterSelectors"
      paasb-search-box-filter-operators="searchctrl.sFilterOperators"
      paasb-search-box-enable-grouping="true">
    </paasb-search-box>

and inside the controller I basically pasted pretty much everything about the example:

var vm = this;

vm.sOptions = {};

vm.sFilters = [
          {
            'name': 'folder',
            'displayName': 'folder',
            'root': 'Column',
            'suggestedValues': [
                    'Test folder',
                    'asd',
                    'asd1',
                    'asd2'
                ],
            'restrictedSuggestedValues': true,
            'multi': true
            //, 'notFiltered': true
          }, {
            'name': 'name',
            'displayName': 'Name',
            'root': 'Column'
          }, {
            'name': 'desc',
            'displayName': 'Desc',
            'root': 'Column'
          }, {
            'name': 'output',
            'displayName': 'Output',
            'suggestedValues': [
                  '(*.xls)',
                  '(*.mdb)',
                  '(*.txt)',
                  '(*.xml)'
                ],
            'restrictedSuggestedValues': true,
            'root': 'Column'
          }, {
            'name': 'model',
            'displayName': 'Model',
            'suggestedValues': [
                  'yes',
                  'no'
                ],
            'restrictedSuggestedValues': true,
            'root': 'Column'
          }, {
            'name': 'pubblic',
            'displayName': 'Pubblic',
            'suggestedValues': [
                  'yes',
                  'no'
                ],
            'restrictedSuggestedValues': true,
            'root': 'Column'
          }, {
            'name': 'editing',
            'displayName': 'Editing',
            'suggestedValues': [
                  'yes',
                  'no'
                ],
            'restrictedSuggestedValues': true,
            'root': 'Column'
          }, {
            'name': 'type',
            'displayName': 'Type',
            'suggestedValues': [
                  'C',
                  'R',
                  'T',
                  'U',
                  'C'
                ],
            'restrictedSuggestedValues': true,

        {

        {

      vm.sFilterSelectors = [

          "notAllowed": [
            "restrictedSuggestedValues"

        {
          "name": "Does not contain",
          "key": "doesNotContain",
          "notAllowed": [
            "restrictedSuggestedValues"

        },
        {
          "name": "Is Equal To",
          "key": "isEqualTo"
        },
        {
          "name": "Is Not Equal To",
          "key": "isNotEqualTo"

        {
          "name": "Starts with",
          "key": "startsWith"
        },
        {
          "name": "Ends with",
          "key": "endsWith"
        },
        {
          "name": "Similiarity",
          "key": "similiarity"
        }
      ];

But when I click the filter button no row is shown, and taking a look at the console I saw no error thrown; taking a look to the HTML elements, I found inside the ng-repeat in charge to render the possible filters no one of its rows satisfies the ng-if="filter.notFiltered" condition, thus they are all out of the DOM.
Finally, inspecting the filters array, this property is missing in every filter object.

Please help me find what am I doing wrong.
Thank you in advance
