Form adding data twice, Grid only inserts once

Suite and Optimus Suite 5
#1

We are using a Grid and Form on the same page to take some user input, when we add a new row and enter data in the grid we only see 1 row appear in the DB, when we add the new data in the form and hit Save we get 2 rows added to the DB.
Can anyone suggest why?
Thanks

dhtmlxEvent(window,"load",function(){

function sort_custom(a,b,order){
var n=a.length;

    return n>m?1:-1;
else
    return n<m?1:-1;

Clicking on the “newContact” button:

if(id=="newContact"){

you add the record to the grid:

 ClientCircuitGrid.addRow(rowId,["New Customer","",""],pos);

which triggers the dataprocessor to send data to the database:
as the dataprocessor is assigned to the grid

dpg.init(ClientCircuitGrid);

and then you send the data again to the database from the form.save():

ClientCircuitForm.save();
