jsf 2 - JSF: Datatable is not updating -

i learning jsf , stuck on below problem:

xhtml class:

    <h:form><p:inputtext  value="#{tempview.tempname}" e:placeholder="search name">     </p:inputtext>     <p:commandbutton id="search" value="search" action="#{tempview.searchname()}" update="datatable">     </p:commandbutton>     <p:commandbutton value="clear" action="#{tempview.clearsearchcriteria()}" update="datatable">     </p:commandbutton>   <p:datatable id="datatable"     value="#{tempview.tmplist}"     var="tempvar" rowstyleclass="#{tempview.rowstyleclass(tempvar)}"     rows="12" paginator="true"     paginatortemplate="{currentpagereport} {firstpagelink} {previouspagelink} {pagelinks} {nextpagelink}     {lastpagelink} {rowsperpagedropdown}"     rowsperpagetemplate="5,10,15" scrollable="true">      <p:column headertext="first name" sortby="#{tempvar.firstname}">         <h:outputtext value="#{tempvar.firstname}" />     </p:column>      <p:column headertext="last name" sortby="#{tempvar.lastname}">         <h:outputtext value="#{tempvar.lastname}" />     </p:column>      <p:column headertext="institute / practice name" sortby="#{tempvar.address}">         <h:outputtext value="#{tempvar.institutename}" />     </p:column> </p:datatable> 

java class:

public string searchname() {      system.out.println("executed");       /**          logic of refining list..     **/ 

}

the issue facing is..first calling getter , setter method , action 'searchname' , after executing action method. not calling getter , setter due datatable not updating. action method 'searchname' have logic of refining list in datatable. please let me know if need other information. thanks.

instead of using action , use actionlistener. need change method in bean return void , add actionevent paramter.
