how to wrap parameters with Data attribute from ajax get call

please look at the code below. the web method is not firing when i wrap "data" attribute in double quotes(" ")

like [   data:    " { 'Name' : '4' } "    ]  in ajax call. am wrapping in quotes because i have to pass textbox data dynamically.let me know the reason pls.

 $('#txt').keypress(function () {
            var date1 = $('#txt1').datepicker().val();
         
            var x = 10;
            $.ajax({
                type: "GET",
                url: "school.aspx/GetEmployees",
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                data: "{'name':'"+date1+"'}",     [Note: it is working like this( { ' Name ' : ' 3 ' } )
                success: function (data) {
                    $("#gvEmployees").empty();
}
});
});
