get error when create button in datagrid toolbar

[pams]

hi everyone..

how to overwrite refresh button in datagrid..?
i used code like this:

var pager = $('#dataObject').datagrid('getPager');    // get the pager of datagrid
pager.pagination({
    showRefresh:false,
    buttons:[{
        iconCls:'icon-reload',
        handler:function(){
            $('#find').searchbox('setValue','');
            reLoad();
        }
    }]
});

i combine my project with Inspinia Template.
and i get error:

Uncaught TypeError: Cannot read property 'panel' of undefined
    at Object.getPager (<anonymous>:11965:32)
    at r.fn.init.$.fn.datagrid (<anonymous>:11815:35)
    at <anonymous>:4:30
    at p (jquery-3.1.1.min.js:2)
    at Ia (jquery-3.1.1.min.js:3)
    at r.fn.init.append (jquery-3.1.1.min.js:3)
    at r.fn.init.<anonymous> (jquery-3.1.1.min.js:3)
    at S (jquery-3.1.1.min.js:3)
    at r.fn.init.html (jquery-3.1.1.min.js:3)
    at Object.success (action.js:84)

can i combine Inspinia template with easyui..?

thanks a lot.

Override the $.fn.pagination.defaults.nav to rewrite the 'refresh' logic.

Code:

$(function(){
	var pager = $('#dataObject').datagrid('getPager');    // get the pager of datagrid
	pager.pagination({
		nav: $.extend({}, $.fn.pagination.defaults.nav, {
			refresh: {
				iconCls: 'pagination-refresh',
				handler: function(){
					console.log('refresh')
				}
			}
		})
	});
})
