Update outputtext value in pageblocktable using javascript

Hello All,

I have created a VF page having pageblocktable tag. There are 2 coulmns, first is apex:input and other is apex:outputtext. On input tag using onchange executing a javascript. In this javascript I am using apex:input value and calculating a outputtext value using a formula. I am getting correct formula value but not able to update in outputtext. Please find VF for ref.
<apex:page standardController="Account" tabStyle="Account" extensions="MonthlyDeductionsController" docType="html-5.0" sidebar="false" id="pageid">
    <apex:sectionHeader title="{!}"/>
    <apex:form id="formid" >
        <script type="text/javascript">
        function changeesi1(input, er, er_rate, inx)
            erid = er;
            er = document.getElementById(erid).value;
            document.getElementById(erid).value = Math.ceil(input.value * er_rate/100);;

            <apex:pageBlockTable value="{!deductiondata}" var="ddlist" id="ddid">
                <apex:column headerValue="ESI Wages 1">
                    <apex:input id="esiwgid1" size="10" value="{!ddlist.ESIWages}" onchange="changeesi1(this, '{!$Component.ER}', '{!currentPeriod.ESI_ER_Rate__c}', '{!ddlist.index}');" />

                <apex:column headerValue="ESI ER({!currentPeriod.ESI_ER_Rate__c}%)" id="erc">
                    <apex:outputText id="er" value="{0, number, Rs #####0.00}">
                        <apex:param value="{!ddlist.ER}"/>
It should update/refresh {!ddlist.ER} value using javascript immidiately after onchange. Could you please tell what is missing in javascript?

I have achieved this using apex function using actionFunction but process is slow and want to calculate and refresf {!ddlist.ER} value in page it self using javascript function instead of apex function. Please let me know if you need more details.

You cannot simply get the element by using "document.getElementById(erid)" in salesforce because salesforce adds some prefix to ids. I think  you can do it like this.

document.getElementById('{!$}').innerHTML = Math.ceil(input.value * er_rate/100);

(innerHTML because outputText will b rendered in to a span)

Let me know if this helps you.
