Add/Delete table rows dynamically using JavaScript

I'm trying to add/delete table rows following this example and this example.

Here's my code:

HTML Form

<div id="POItablediv">
    <input type="button" id="addPOIbutton" value="Add POIs"/><br/><br/>
    <table id="POITable" border="1">
        <tr>
            <td>POI</td>
            <td>Latitude</td>
            <td>Longitude</td>
            <td>Delete?</td>
            <td>Add Rows?</td>
        </tr>
        <tr>
            <td>1</td>
            <td><input size=25 type="text" id="latbox" readonly=true/></td>
            <td><input size=25 type="text" id="lngbox" readonly=true/></td>
            <td><input type="button" id="delPOIbutton" value="Delete" onclick="deleteRow(this)"/></td>
            <td><input type="button" id="addmorePOIbutton" value="Add More POIs" onclick="insRow()"/></td>
        </tr>
    </table>
</div>

JavaScript

function deleteRow(row)
{
    var i=row.parentNode.parentNode.rowIndex;
    document.getElementById('POITable').deleteRow(i);
}


function insRow()
{
    var x=document.getElementById('POITable').insertRow(1);
    var c1=x.insertCell(0);
    var c2=x.insertCell(1);
    c1.innerHTML="NEW CELL1";
    c2.innerHTML="NEW CELL2";
}

Now, as you can see, In my table I have text fields and buttons. What I want:

  1. Just to repeat the structure of the row. I can't do it right now since innerHTM just takes texts. How can I insert a textfield or label?

  2. The ids of the textfields should also be different since I'll retrieve the values later to put it in a database.

  3. I want to put a function to increment the number of POIs as well

Can anyone help me out please?
