Add New Row to SlickGrid

Add New Row to SlickGrid

Hi i have tried these two codes for inserting a new row in slickgrid.
code-1:
data1.push({id: "12345", name: "secKey", field: "secKey", complete:true});
//grid1.setData(data1);
//grid1.render();
it is inserting as undefined in the slick grid cell..
code-2:
try{
var rowData = grid1.getData();
//alert(rowData+"rowdata");
newId = dataView1.getLength();
//alert(newId);
newRow.id = newId + 1;
//alert(newRow.id);
var newRow = {title: "new Title"};
//alert(newRow);
dataView1.insertItem(newRow.id, newRow);
alert("end");
}catch(e){
alert("error:"+e.description);
}
the code-2 catches and gives error..let me know wat i have to do code
change.!
