I think a simple ng-if in your table and then putting your data gathering code into a function would do it.

<table ng-if="dtColumnsReject" width="100%" id="declined-table" datatable="" dt-options="dtOptionsReject" dt-columns="dtColumnsReject" class="table table-bordered table-hover">
                            </table>    


<button ng-click="loadTable()"> load table </button>

$scope.loadTable = function() {
$scope.dtOptionsReject = DTOptionsBuilder.newOptions()
            .withOption('ajax', {

            .... all your code ....

          '</div>';
        }).withClass('text-center').notSortable()
    ];
   
 }
