Custom action buttons and onUserRowSelect called at the same time

For example ,
I have some custom actions(add resources , edit resources ,delete resources , add images) defined in ng2-smartTable which will open a modal on button click ,the issue was when i added onUserRowSelect which is supposed to display the row content in a modal . So when i click on the action buttons -> 'onUserRowSelect' is first called and then the button action modal is called .
