thanks in advance

update

i found solution of problem, did create own filter:

filter="{ 'client': 'clienttext' }"

...

<script type="text/ng-template" id="ng-table/filters/clienttext.html">             <input type="text" name="filter-clienttext" ng-model="params.filter().clientclient.libelle" class="input-filter form-control"/>         </script> 

thanks :)
