    var oValue = oEvent.getSource().getValue();
    var oValue2 = oEvent.getSource().getValue2();
    
    if(oValue > oValue2)
    {
    
    oEvent.getSource().setValue(oValue2-3);
    oEvent.getSource().setValue2(oValue2);
    
    }
    
    else if (oValue2 < oValue1)
    {
    
    oEvent.getSource().setValue2(oValue1+3);
    oEvent.getSource().setValue(oValue1);
    
    }
}

It doesn't update tooltip texts.
The tooltip texts of value and value2 should update on change event and setting value and value2 but it doesnt get updated.Any way tooltip can be updated.What happens now is after change event if it reaches a condition we set value and value2 but tooltip doesn't get updated and shows old values of value and value2

Kindly suggest how can i updated tooltip values. Is it a bug from standard control sap.m.RangeSlider ?
