You don't have a resistor to define the input voltage.
As it is, this voltage will be determined by the leakage current of the IC & the leakage resistance of the 100 nF cap.
Both will be small, but if you leave the circuit powered for several days, you may find it has changed state.
That is why the circuit with a 4M7 feedback resistor is better.
However, I don't know if you want it to toggle or not.
In other words, do you want to be able to switch the LED on & then press the TP later to switch it off?
Or do you want the LED to be on only while you're pressing the TP?
