Question:Inserting a Plots component in the Exploration Assistant

I have

>a*x^2-(b+a)*x+b;

right-click the expression and choose Explore.  Skip "x" so we have two sliders (a and b)

Select a=-2 and b=0.  In the Math component, you will have

a*x^2-(b+a)*x+b =-2*x^2+2*x
Now, under the two sliders, I add a PLots component.  My wish is to plot the rhs(%Math). 

 In the plot component properties, I edit the "Action when clicked" and write

 Do(%Plot0=plot(ths(%Math),x=-2..2));

Now, when I click the first time on the Plot component, the plot is  -2*x^2+2*x.
But if I move a slider, the plot doesn't update to reflect the change.

Any ideas?
