+This javascript will validate/allow the number only when event key is pressed.
+
+{% highlight html %}
+<input id="id_price" type="number" min=0 />
+<script type="text/javascript">
+function isNumber(evt) {
+    evt = (evt) ? evt : window.event;
+    var charCode = (evt.which) ? evt.which : evt.keyCode;
+    if (charCode > 31 && (charCode < 48 || charCode > 57)) {
+        return false;
+    }
+    return true;
+}
+document.getElementById('id_price').setAttribute("onkeypress", "return isNumber(event)");
+</script>
+{% endhighlight %}
+
+
+For example result of it:
+
+<script async src="//jsfiddle.net/agaust/3qz105nn/embed/html,result/dark/"></script>
