Help! I am Using Vs code and it doesn't recognize ejs tags.

I am Using Vs code it doesn't recognize ejs tags when they are inside an html tag like the input tag below :

<input type="checkbox" name="checkbox" value="<%=item._id%>" >
Before changing the default value property from on to <%=item._id%> it would actually print on, Now it does nothing !
and in the code itself i can see that it doesn't recognize it because the color doesn't change as usual.

Any suggestion is appreciated.
