html

<li ng-repeat="cat in categoryarray">     <label>     <input type="checkbox" ng-model="cat.on" ng-change="checkchange()" />{{cat.name}}</label> </li> <hr> <h1><strong>category:</strong></h1>  <div ng-repeat="sessionitem in sessionarray | filter:myfunc | orderby: 'id'" class="ng-scope">     <h3>{{sessionitem.name}}</h3> </div>

demo

to nest filter add pipe | , use "filter" filter normally.

<div ng-repeat="sessionitem in sessionarray | filter:myfunc | filter:thefilter | orderby: 'id'">

check example here.
