How to do ng-model in this case, where I have only one input?

Question

I have this code in .pug:

div(class="box-group" ng-controller="filter")

    div(class="panel box box-primary col-sm-12")
        div(style="text-align:center")
            h4 Filtro    
        div(class="form-group col-sm-12")
            label Selecionar Banco:
            select(class="form-control")
        div(class="col-sm-12")
            br
            div(id="treeview")
              script#item-template(type='text/x-kendo-template').
                # if (data.item.showCombo) { #
                #= data.item.text #
                <input text ignoreCss="True" k-ng-model=data> 
                # } else { #
                #= data.item.text #
                # } #

        div(class="modal-footer")
            button(type="button" class="btn btn-primary" ng-click="confirmar()") Confirmar

And this on .js I need to save what’s in the objects, using ng-model. How to do it, since I only have one input?

angular.module('app').controller(
    'filter',
    ['$scope', '$ftHttp', 'ngToast', '$location', '$filter',
        function ($scope, $ftHttp, ngToast, $location, $filter) {
            $(function () {
                $("#treeview").kendoTreeView({
                    dataSource: {
                        data: [{
                            text: "ID",
