SAPUI5 onSearch() Filter update - sapui5

Question

Somehow my filter update through the function onSearch is not updating the view. The initial Filter in the XML View is working fine. Also when sIaNr is empty the aFilter = [] is working as I'm seeing all results. But when sIaNr is not empty this part is called and the filter is not working:
aFilter.push(new Filter("raufnr", FilterOperator.EQ, sIaNr))
this is my Code
ZCATS_TESTJ.json
{
"d": {
"results": [{
"status": "30",
"skostl": "0001",
"catshours": "2.50",
"ktext": "test1",
"counter": "000003484040",
"mandt": "101",
"pernr": "00015822",
"usrid": "xx123",
"workdate": "\/Date(1477267200000)\/",
"raufnr": "6000025"
}, {
"status": "30",
"skostl": "0001",
"catshours": "8.00",
"ktext": "test2",
"counter": "000002919281",
"mandt": "101",
"pernr": "1234",
"usrid": "xx123",
"workdate": "\/Date(1441065600000)\/",
"raufnr": "0815"
}, {
"status": "30",
"skostl": "0001",
"catshours": "8.00",
"ktext": "test1",

"usrid": "xx123",
"workdate": "\/Date(1441065600000)\/",
"raufnr": "6000007"
}]
}
}

any help would be greatly appreciated. Thanks

Delete 'sap/ui/core/util/MockServer' in the define part.
