Meteor WebSocket Filter with reactive change not working?

export default class RegistroPersonas extends TrackerReact(React.Component) {

constructor(props) {
super(props);
this.state = {
subscription: {
pacientes: Meteor.subscribe(“pacientes”)
}
}
}

shouldComponentUpdate(nextProps, nextState) {
if (this.props === nextProps) {
return false;
}
}

componentWillUnmount() {
this.state.subscription.pacientes.stop();
}

data() {

return Pacientes.find({nombre : new RegExp(this.state.nombre, 'i')}).fetch(); 

}

render(){

let mario = this.data();

return(
        <MuiThemeProvider >

          <div>
              <Grid>                  
                  <div className='segurosMedicos'>
                    
                      
                      <Row>
                          {mario.map((ob) => { return <PersonasRows key={ob.inx} objeto={ob} /> } ) } 

                      </Row>
                      <DialogAgregarPersonas />
                  </div>
              </Grid>
          </div>

        </MuiThemeProvider>

  )

}
}

Good day,

I am trying to apply a filter on the data I return with the subscription when I apply a filter to this.state.nombre 

 return Pacientes.find({nombre : new RegExp(this.state.nombre, 'i')}).fetch();  << 

Does not update 

Row>
                              {mario.map((ob) => { return <PersonasRows key={ob.inx} objeto={ob} /> } ) } 

                          </Row>

if I force the rerender then the filter will get deleted if I add a new value to the Pacientes collection I will get a new Row but if I apply a filter it won't short the list if I apply the filter manually it works 

 return Pacientes.find({nombre : new RegExp(/j/i)}).fetch();

Any other way I could make react notice the change and update according to filter? the only way I think of.. it is making another component with the data I need and sending it a prop to force an update but seems like not the right way of doing it? 

Help?? :blush:
