Same to #8033 TICKET--Extra button appears

I have Array.prototype.myfunction

There is another button called myfunction appears to the dialog.

If I close the dialog and open again, this extra button disappeared.

$("#dlg").dialog({ width: 380, height: "450", title: "Set xxx", modal: true,

buttons: [

{ text: "Update",

click: function () {

crm_price_obj.change_tracker(mk,tracker,ln);

}

},

{ text: "Cancel",

click: function () {

$(this).dialog("close");

}

}

],

open: function () {

myoption = $("#add_budget_dlg > table > tbody > tr[tid='" + tracker + "'] > td > input[name='chk_budget']").attr("checked", "checked");

}

});
