Apex repeat function here would repeat the days of the week, iterating from Monday to Sunday also displaying the day alongside.

My problem is in the prevWeek.

prevWeek is a button. (supposed to be)

When it is clicked I want the changes in goprev to take place.

I need wcTopBar to display the previous weeks days.

Pl take a look at

 <apex:actionSupport event="onclick" action="{!goprev}" rerender="wcTopBar" />  

and let me know what is deficient to do the job.

<apex:outputPanel id="wcTopBar" layout="block" styleClass="containerAD noscroll" style="height: 37px;">
                                    <div class="overflowContainer">    
                                        <div class="weekLabels">
                                            <apex:repeat value="{!daysOfWeek}" var="d">
                                                <div class="{!d.divClass}">
                                                  ​  <div><span style="{!d.spanStyle}"><apex:outputText value="{!d.dayName}" escape="false" /></span></div>
                                                  ​      </div>
                                            </apex:repeat>
