In Odoo 11.0 i use this method to write a field of a model.
How can i achieve the same in odoo 10?
Is good a link with a good explanation.

function update_line_value(checklist_line_id, checklist_line_view_id) {

    //Take the id of the checklist line
    var checklist_line_id_int = Number(checklist_line_id);
    var value = $('#' + checklist_line_view_id).val();
    var task_id_int = Number($("input[name='task_id']").val());
    //Search and hr.expense with this product_id
    rpc.query({
        model: "sale.order.checklist.line",
        method: "write",
        args: [checklist_line_id_int, {answer_yes: value}],
    }).then(setTimeout(function () {
        //Set a delay or the update is not visible
        window.location.reload(true);
    }, 300));
}
