JsGrid : Load grid data from local variable

I want to make a CRUD web application with JsGrid and Express.js. Server side render data to a jade file. Then I send data to a JavaScript file that use JsGrid. So I send my data in a fonction parameter and I want to load that data to my JsGrid in the ajax function.

Thank you for your help.

///// My code begins here

function load_data(clientsData){

$("#clients").jsGrid({
    height: "auto",
    width: "1000px",
    filtering: true,
    inserting: true,
    editing: true,
    sorting: true,
    paging: true,
    autoload: true,
    pageSize: 10,
    pageButtonCount: 5,
    deleteConfirm: "Do you really want to delete client?",
    controller: {
        loadData: function(clientsData) {
            return $.ajax({
                type: "GET",
                url: "/clients",
                data: clientsData
            });
        },

    },

});

}
