Enter Text into Kendo Textbox with Protractor

I'm trying to use Protractor to enter text into a Kendo TextBox, but I get an error "ElementNotVisibleError: element not visible". When you click on the text box, the "style="display: none;" changes to "style="display: inline-block;" if that helps.

<input type="text" class="k-formatted-value k-input" tabindex="0" aria-disabled="false" aria-readonly="false" style="display: inline-block;">
<input kendo-numeric-text-box="" k-options="numericConfig" k-ng-model="somemodel" data-role="numerictextbox" role="spinbutton" class="k-input" type="text" aria-valuenow="323423" aria-disabled="false" aria-readonly="false" style="display: none;">

How would I sendKeys to this text box?

Thanks so much!
