easyui combogrid 分页问题

[lansecheng]

点击翻页可以有返回的json，但是表哥内容没有刷新
var grid=$('#hourse4').combogrid('grid');
var pager=$(grid).datagrid('getPager');
$(pager).pagination({
onSelectPage:function(pageNumber, pageSize){
var queryParams = $(grid).datagrid('options').queryParams;
queryParams.page = pageNumber;
queryParams.rows =pageSize;
$(grid).datagrid('reload');

},
onChangePageSize:function(){
var queryParams = $(grid).datagrid('options').queryParams;
queryParams.page = pageNumber;
queryParams.rows =pageSize;
$(grid).datagrid('load');
}
});
