Update JSF datatable without refreshing the page

I have input fields and datatable in the same page, in such a way that when user adds a new data, data should be added to the datatable without refreshing the page.

To achieve this I tried the following code

xhtml part

<table border="0">
        <tr>
            <td width="700" height="100px">Customer Name: <h:inputText
                immediate="true" id="customername" autocomplete="false" value="#{salesBean.customerName}">

            </h:inputText> 

            </td>
        </tr>
        <tr>
            <td width="900" height="160px">
            <table border="1">
                <tr>
                    <td align="left">Product Name</td>
                    <td align="left">Rate</td>
                    <td align="left">Quantity</td>
                    <td align="left">Total Price</td>
                    <td align="left">Paid</td>
                    <td align="left">Date of Sales</td>
                    <td align="left"></td>
                </tr>
                <tr>
                    <td align="left"><h:inputText immediate="true"
                        id="productname" autocomplete="false" value="#{salesBean.productName}">


                    </h:inputText></td>
                    <td align="left"><h:outputText id="rate"
                        binding="#{salesBean.productRate}" /></td>
                    <td align="left"><h:inputText size="2"
                        onkeyup="return calculateTotalRate(event);" id="quantity" value="#{salesBean.quantity}"/></td>
                    <td align="left"><h:outputText id="totalprice" /></td>
                    <td align="left"><h:selectOneRadio  id="sor"
                        title="Select any one of the choice" value="#{salesBean.paidFlag}">
                        <f:selectItem id="si1" itemLabel="Yes" itemValue="yes" />
                        <f:selectItem id="si2" itemLabel="No" itemValue="no" />
                    </h:selectOneRadio></td>
                    <td align="left"><rich:calendar id="salesDate" value="#{salesBean.salesDate}"></rich:calendar></td>
                    <td align="center">
                    <h:commandButton value="Submit">

                    <h:commandButton value="Cancel" /></td>
                </tr>
            </table>`

            </td>
        </tr>
    </table>

Please help me to solve this. Please update me if my question is not clear.

I am using JSF 1.2 and Richfaces 3.3.2

Thanks in advance

You have missed event attribute in a4j:support. Should be like this (disableDefault="true" is to prevent h:commandButton standard behavior):

<h:commandButton value="Submit">                        
    <a4j:support event="onclick" disableDefault="true" action="#{salesBean.submit}" reRender="table"/>
</h:commandButton>

Or even better like this (will do the same as the lines above, but in more a4j-style):

<a4j:commandButton value="Submit" action="#{salesBean.submit}" reRender="table"/>

"Without refreshing the page" means AJAX.

RichFaces 3.3 has AJAX support, and their documentation explains how to use it in chapters 5.1 through 5.7.
