You may use either actionSupport or actionFunction. actionFunction example is given below.

e.g.
<script type="text/javascript">
function clearTextJS()
{
    clearTextAF();
}
</script>

<apex:page>...
<apex:actionFunction name="clearTextAF" action="{!clearText}" immediate="true"/>
<apex:inputTextarea rows="1" id="inputpa" value="{!ebrecs.Attendance_Notes__c}" onclick="clearTextJS();"/>


Define method clearText() in Controller/Extension. You may either use rerender with actionFunction or return a PageReference from the method clearText().
