title: Restrict user entering more decimals than in Numerictextbox's configuration
body: <p>I want to restrict users decimal inputs when configured as decimals in <code>Numerictextbox</code>. I'm using knockoutjs to observe the data from numerictextbox. When the user enters more decimal it's automatically updated in knockout, but in control it shows only the configured decimals.</p>
  
  <p>Decimals are set dynamically to kendo numerictextbox, so I need to restrict user input decimals when its more of defined decimals. When user enter in a number of decimals knockout updates that value</p>
  
  <p>One example is if I set decimals to 2. When the user enters <code>56.2456</code> knockout updates this value in the model, and after the cursor moves to the next control numerictextbox shows <code>56.25</code>. I want to update this value into the model and need to restrict user entering more then 2 decimals.</p>
  
  <p>How can I apply this restriction?</p>
