  <input type="text" ng-model="valuesforoutputs[item.name][i]"                 ng-disabled="isdisabled(item.name, i)" ng-pattern="/^(\d)+$/"                                required   name="value"                                                placeholder="enter value">        <span class="error pop_up" ng-show="targetform.value.$error.pattern">please enter number</span> 

you can use onkeypress event of textfield:

 var allowonlynumbers=function(field){          if (!string.fromcharcode(event.keycode).match('[0-9.]') || (field.value.match('[.]') && string.fromcharcode(event.keycode) == '.'))             event.preventdefault();      };

 <input onkeypress='allowonlynumbers(this)' type="text" ng-model="valuesforoutputs[item.name][i]"                  ng-disabled="isdisabled(item.name, i)" ng-pattern="/^(\d)+$/"                                 required   name="value"                                                 placeholder="enter value">
