Internet Explorer - No refresh without F12 Tools

Hi experts,

very strange behaviour:

I have a table (sap.ui.table.Table), with binding to a gateway service (bindRows("/testSet").

I added 3 buttons above the table, which will add a filter to the table

var oJobSelectionAk = new sap.ui.commons.Button({
text : "Aktiv", 
press: function() {
var oFilter = new sap.ui.model.odata.Filter('status', [ {
operator : sap.ui.model.FilterOperator.EQ,
value1 : "R"
} ]);
oTable.bindRows({ 
path: "/jobsSet",
filters : [ oFilter ]
});
}
} );

As you can see, it adds a filter "status EQ "R".

This is working fine in Chrome, table gets refreshed.

It is NOT working in IE, table doesn't refresh. BUT, if F12 tools are opened, everything is working.

Does anyone know what I can do here?

Thanks

Michael
