Preventing Jade from adding an assignment clause in an HTML element

Question

I want to define a local variable in an input tag for an Angular 2 application:

input(#sometext)
button((click)="addTechnology(sometext.value)") Add

The output that I am expecting is:

<input #sometext/>
<button (click)="addTechnology(sometext.value)">Add</button>

However the real output is (notice the additional ="#sometext"):

<input #sometext="#sometext"/>
<button (click)="addTechnology(sometext.value)">Add</button>

This way, Angular 2 throws the following error, very likely due to that ="#sometext":

Cannot find directive with exportAs = '#sometext'

Do you know any way of preventing Jade from completing the attribute with the additional ="#sometext"?

Answer 1

In the end it was as simple as using doctype html at the beginning of the Jade template. I had it in the main layout but it seems that the included files also need it.
