AngularJS repeat filter from input
<p>I have a problem. I have this code but it does not work why? It works in an other project. I have a table and filter it with an input field.            </p>

<pre><code>&lt;md-content class="md-padding"&gt;
    &lt;br&gt;
    &lt;md-input-container&gt;
        &lt;label&gt;search&lt;/label&gt;
        &lt;input ng-model="searchCManager" placeholder='lss_user_id'&gt;
    &lt;/md-input-container&gt;
    &lt;table class='table'&gt;
        &lt;thead&gt;
        &lt;tr class='header'&gt;
            &lt;td&gt;user_id&lt;/td&gt;
            &lt;td&gt;start_number&lt;/td&gt;
            &lt;td&gt;lss_user_id&lt;/td&gt;
            &lt;td&gt;agency_number&lt;/td&gt;
            &lt;td&gt;business_unit_number&lt;/td&gt;
            &lt;td&gt;office_id&lt;/td&gt;
            &lt;td&gt;corporate_id&lt;/td&gt;
            &lt;td&gt;asw_id&lt;/td&gt;
        &lt;/tr&gt;
        &lt;/thead&gt;
        &lt;tbody&gt;
        &lt;tr ng-repeat="x in terminalOverview | filter:searchCManager " ng-class="{'noTerminal': x.terminals.length == '0' || x.terminals.length == 'terminal'}"&gt;
            &lt;td&gt;{{ x.user_id }}&lt;/td&gt;
            &lt;td&gt;{{ x.start_number }}&lt;/td&gt;
            &lt;td&gt;{{ x.lss_user_id }}&lt;/td&gt;
            &lt;td&gt;{{ x.agency_number }}&lt;/td&gt;
            &lt;td&gt;{{ x.business_unit_number }}&lt;/td&gt;
            &lt;td&gt;{{ x.office_id }}&lt;/td&gt;
            &lt;td&gt;{{ x.corporate_id }}&lt;/td&gt;
            &lt;td&gt;{{ x.asw_id }}&lt;/td&gt;
        &lt;/tr&gt;
        &lt;/tbody&gt;
    &lt;/table&gt;
&lt;/md-content&gt;
