i solved it by combining, if somebody need:
function linkFormat2(cellvalue, options, rowObject) {
var cellValueInt = parseInt(cellvalue);
if (cellValueInt = "mobile")
{
var linkUrl = '@Url.Action("GetMobilePhoneModels", "MobilePhoneModel", new { phonenumber = "Id" })'.replace('Id', rowObject['PhoneNumber']);
return '<span class="MobilePhoneModel"><a href="' + linkUrl + '"><img src="../../Content/Images/Devices/mobile.png" width="11px" height="20.75px" alt="' + cellvalue + '" title="' + cellvalue + '" /></a></span>';
}
}
