using, this.state.mystate in react within meteor spits out reference errors. Whats happening.?

btw I just want to rerender my component by toggling state rather than use forceUpdate()

"Basically you don't call setState yourself, the component updates itself when the data changes" -->how do achieve a rerender in meteor then?

using forceUpdate()`shows this error:

Exception in delivering result of invoking 'login.js': TypeError: this.forceUpdate is not a function
