try this:

your form tag should be like this <h:form> because you are using h:commandButton tag and your p:dataTable tag should be inside h:form tag. Write method name in EL without parenthesis.

<h:body> 
    <div id="wrapper">
    <div id="header">
        <h2>Mood Watch</h2>
    </div>
    </div>

    <h:form>
        <p:outputLabel>Filter : </p:outputLabel>
         <p:selectOneMenu id="whySelect1" value="#{hibernateController.siteFromMood}">
                 <f:selectItems value="#{hibernateController.mySites}" var="tempSites" itemLabel="#{tempSites.site}" itemValue="#{tempSites.moodSite}" />
            </p:selectOneMenu>
<h:commandButton value="Filter" actionListener="#{hibernateController.filterSites}"/>

                <h:commandButton value="View All" actionListener="#{hibernateController.setSitMoodToNull}"/>



    <p:dataTable id="moodTable" var="moodValues" value="#{hibernateController.myFrontEndModels}">
        <p:column headerText="Date">
            <h:outputText value="#{moodValues.dateCreated}" />
        </p:column>

        <p:column headerText="Site">
            <h:outputText value="#{moodValues.sitename}" />
        </p:column>

        <p:column headerText="Value">
            <h:outputText value="#{moodValues.moodValue}" />
        </p:column>

    </p:dataTable>


 </h:form>
</h:body>

Trust I have tried that as well I just took it out because the table has nothing to do with the form the table just renders data , but I just tried it again and didnt work — user3701188, Jan 31 '17 at 14:27
Can you upload your full backing bean code that contains the methods?? — ArgaPK, Jan 31 '17 at 14:29
Thank you soo much bruh, I spent 2 hours on this can you imagine — user3701188, Jan 31 '17 at 14:44

Thanks for answering, but please search for duplicates of 'basic' issues. Lots of those already have Q/A in Stackoverflow http://stackoverflow.com/questions/2118656/commandbutton-commandlink-ajax-action-listener-method-not-invoked-or-input-value — Kukeltje, Jan 31 '17 at 15:29
