ContractWithModifier.sol has two issues: (1) uses incorrect way to call modifier, and (2) forgets to use modifier

[zallanx]

The following code has errors (comments added to show)

function AssignDoubleValue(int _data) public isOwner { //should be called as isOwner()
        mydata = _data * 2;
}

function AssignTenerValue(int _data) public  { //forgot to call isOwner()
        mydata = _data * 10;
}

Author should update the code to reflect errors.
